The WordPress White Screen of Death (WSoD) is a frustrating issue where your site or parts of it turn completely blank – no error messages, no clues. It can affect your entire website, specific pages, or even the admin dashboard. This guide explains the most common causes and step-by-step solutions to fix it.
Key Causes of WSoD:
- Plugin or Theme Conflicts: Often triggered by updates or poorly coded extensions.
- PHP Memory Limits: Insufficient memory allocation can halt site operations.
- Corrupted Core Files: Issues within critical WordPress files like
functions.phpor.htaccess. - Server-Side Issues: Hosting problems such as high CPU usage or low disk space.
Quick Fixes:
- Clear Browser Cache: Sometimes the issue is local.
- Disable Plugins: Deactivate all plugins via the dashboard or rename the plugins folder using FTP.
- Switch Themes: Revert to a default WordPress theme like Twenty Twenty-Four.
- Increase PHP Memory Limit: Edit
wp-config.phpor.htaccessto allocate more memory. - Enable Debugging: Use
WP_DEBUGinwp-config.phpto identify errors.
If these don’t resolve the issue, advanced steps like repairing the database, checking file permissions, or restoring from a backup may be necessary. Regular updates and backups can help prevent this problem in the future.
Pro Tip: Always test changes one at a time, and keep backups handy to avoid permanent data loss.
How to Fix the WordPress White Screen of Death (Step by Step)
Initial Checks Before Troubleshooting
Before diving into complex fixes, it’s smart to rule out the simple stuff first. By checking your browser, hosting, and site security, you can often pinpoint the issue without making unnecessary changes.
Check Browser and Cache Issues
Sometimes, the culprit behind display problems is as simple as your browser cache or cookies. These stored files can show outdated versions of your site, including old error pages that no longer exist.
Start by clearing your browser’s cache and cookies. If you’re using Chrome, press Ctrl+Shift+Delete (or Cmd+Shift+Delete on a Mac) to bring up the clear browsing data dialog. Select "All time" as the time range, and make sure to check both "Cookies and other site data" and "Cached images and files."
Once cleared, test your site in incognito mode or on a different browser or device. If the site works in incognito mode, the issue is likely browser-related and not a true WordPress error.
Don’t forget about CDN and caching plugins. Services like Cloudflare or plugins like WP Rocket and W3 Total Cache can store outdated cached data. Be sure to clear their caches via their respective dashboards to rule out these as potential causes.
Verify Hosting and Server Status
Server issues can sometimes mimic WordPress problems, like the infamous White Screen of Death. That’s why it’s crucial to check your hosting provider before assuming the issue lies within WordPress itself.
Most hosting providers have status pages where they report outages, maintenance, or performance problems. Check these pages for any reported issues with their servers, databases, or networks. Hosts like SiteGround, Bluehost, and WP Engine usually provide real-time updates.
Log into your hosting control panel to verify that key WordPress files are intact. Review server error logs for signs of trouble, such as PHP errors, memory limits, or file permission issues. Navigate to your site’s root directory (usually public_html or www) and confirm that essential files like wp-config.php, index.php, and the wp-content folder are present and uncorrupted.
If you have SSH access, you can dig deeper by checking server resources directly. High CPU usage, low disk space, or memory exhaustion can all cause white screen errors. Many hosting control panels also include resource usage graphs to help you identify recent spikes or ongoing issues.
Check Site Security
If your hosting and server setup looks fine, it’s time to check your site’s security. Malware or breaches can cause white screens by injecting harmful code, corrupting files, or overloading your server with malicious traffic.
Use security plugins like Wordfence, Sucuri, or iThemes Security to scan for malware. If you can’t access your WordPress dashboard, try online security scanners such as Sucuri’s free website scanner or VirusTotal. Pay close attention to critical files like wp-config.php, .htaccess, and index.php – look for unusual modifications.
You should also check if your site has been blacklisted by search engines or security services. Google’s Safe Browsing checker can help you determine if your site has been flagged for malware or phishing, which often coincides with security issues causing white screens.
Finally, review your access logs for suspicious activity. Watch for strange traffic patterns, repeated failed login attempts, or requests for files that shouldn’t exist. These are often signs of unauthorized access or plugin vulnerabilities being exploited.
If you suspect a security issue, change all relevant passwords immediately. Even if the white screen isn’t caused by a breach, resetting passwords ensures your site remains secure while troubleshooting.
Basic Troubleshooting Methods
Once you’ve ruled out issues with your browser, hosting, or security settings, it’s time to dive into some hands-on troubleshooting. These steps focus on common culprits like plugin conflicts, theme errors, memory limits, and debugging.
Disable All Plugins
Plugins are a frequent cause of the dreaded WordPress white screen. A single incompatible plugin can bring your entire site to its knees, so testing for plugin-related issues is a good starting point.
If you can still access your WordPress dashboard, head to Plugins > Installed Plugins. Use the checkbox at the top to select all plugins, choose "Deactivate" from the bulk actions menu, and click "Apply." This will deactivate all plugins without erasing their settings.
But what if you can’t access the dashboard? In that case, use FTP or your hosting provider’s file manager. Locate the /wp-content/ directory and rename the plugins folder to something like plugins-disabled. This forces WordPress to deactivate all plugins.
Once plugins are disabled, check if your site is back online. If it is, you’ve pinpointed the issue. Rename plugins-disabled back to plugins and reactivate plugins one at a time through the dashboard, testing your site after each activation. When you find the problematic plugin, you can update it, replace it, or reach out to the developer for help.
If plugins aren’t the issue, the next step is to look at your theme.
Switch to a Default Theme
Themes, especially custom ones or those with recent updates, can also cause white screens. Switching to a default WordPress theme can help you figure out if your theme is the problem.
From the WordPress dashboard, navigate to Appearance > Themes and activate a default theme like Twenty Twenty-Four or Twenty Twenty-Three. These themes are rigorously tested and rarely cause problems.
If you can’t access your dashboard, use FTP (e.g., FileZilla or WinSCP) to reach the /wp-content/themes/ folder. Rename your active theme’s folder by appending something like -broken to its name. This disables the theme and prompts WordPress to switch to a default one.
Alternatively, you can use phpMyAdmin to make the change. In your hosting control panel, open phpMyAdmin and locate the wp_options table in your WordPress database. Look for the template, stylesheet, and current_theme entries, and change their values to match a default theme folder name like twentytwentyfour.
If the issue still persists, memory limits might be the next thing to check.
Increase PHP Memory Limit
WordPress can be a memory hog, especially if you’re running multiple plugins, using a large theme, or experiencing high traffic. When your site exceeds its PHP memory limit, you’ll often see a white screen.
To increase the memory limit, edit the wp-config.php file in your WordPress root directory. Add this line just before the /* That's all, stop editing! */ comment:
ini_set('memory_limit', '256M'); Start with 256MB, which is usually sufficient. For more demanding sites, you can try increasing it to 512MB or even 1GB – but check with your hosting provider first, as shared hosting plans often have strict caps.
Another option is to modify the .htaccess file by adding:
php_value memory_limit 256M After making these changes, test your site. If the white screen is gone, the issue was memory-related. However, treat this as a temporary fix. Figure out why your site is consuming so much memory, whether it’s due to bloated plugins, a large theme, or something else.
Enable WordPress Debugging
Debugging can turn a frustrating white screen into a clear error message, helping you identify the exact problem. By default, WordPress hides errors to protect sensitive information, but you can enable debugging to get to the root of the issue.
Open the wp-config.php file and find this line:
define('WP_DEBUG', false); Change it to:
define('WP_DEBUG', true); define('WP_DEBUG_LOG', true); define('WP_DEBUG_DISPLAY', false); This setup logs errors to a file without showing them publicly. The log file will be created at /wp-content/debug.log.
Reproduce the white screen by visiting the affected pages, then check the debug log. You’ll see error messages pointing to specific files and line numbers, such as "Fatal error: Call to undefined function." This information helps you pinpoint whether the issue is with a plugin, theme, or something else.
Once the problem is resolved, disable debugging by setting WP_DEBUG back to false. Leaving it on can slow your site and expose sensitive data.
Restore From a Backup
If all else fails, restoring from a recent backup can quickly get your site back up and running. Just keep in mind that any changes made after the backup will be lost.
Most hosting providers, like SiteGround, Bluehost, and WP Engine, offer automatic backups with one-click restore options. Look for a "Backups" or "Restore" section in your hosting control panel.
If you use a backup plugin like UpdraftPlus, BackWPup, or Jetpack, check its interface for recent backups. These plugins often let you restore your entire site or just specific components like the database or files.
For a manual restoration, use FTP to upload your backup files and phpMyAdmin to restore the database. This method requires some technical know-how but gives you full control over the process.
After restoring, thoroughly test your site to ensure everything works as expected. Double-check key pages, forms, and functionality. Once your site is stable, carefully reapply any recent changes, testing each one to avoid recreating the original issue.

Advanced Troubleshooting Methods
When the basic troubleshooting steps fail to fix your white screen issue, it’s time to try more advanced techniques. These methods address deeper, more complex problems, but with the right guidance, they’re entirely manageable – even if you’re not a technical expert.
Fix Syntax or Coding Errors
Coding mistakes are one of the most frequent causes of persistent white screens, especially if you’ve recently customized your site. Errors in your functions.php file or custom code can bring your entire website to a halt. Common culprits include missing semicolons, mismatched brackets, or incorrect PHP tags.
To start, examine your theme’s functions.php file, which is located in /wp-content/themes/your-theme-name/. If you’ve recently added custom code, that’s likely where the issue lies. Use an FTP client or your hosting provider’s file manager to access the file and look for obvious errors, such as missing closing brackets } or semicolons ;.
If debugging is enabled, your error log will point you to the exact problem. Look for error messages like:
"Parse error: syntax error, unexpected ‘}’" followed by a file path and line number. This will help you pinpoint the issue.
If you can’t find the error, try commenting out recent code additions by wrapping them in /* */ tags. For example:
/* add_action('wp_head', 'my_custom_function'); function my_custom_function() { echo 'Hello World'; } */ After commenting out each block of code, test your site. If the white screen disappears, you’ve found the problematic code. You can then fix the syntax error or remove the code entirely.
For those using child themes, don’t forget to check both the parent and child theme files. Conflicts between the two can arise, especially after updates.
Check File Permissions
Incorrect file permissions can also cause white screens by preventing WordPress from accessing critical files. This issue often occurs after migrating servers, changing hosting providers, or modifying security settings.
WordPress requires specific file permissions to function properly:
- Directories should be set to
755 - Files should be set to
644 - The
wp-config.phpfile should be set to600for security
To adjust permissions, use your FTP client. Right-click on your WordPress root directory and select "File permissions" or "Properties." Apply the correct settings to directories and files. Many hosting providers also offer tools to fix permissions directly from their control panels. For cPanel, use the "File Manager" to adjust permissions. For Plesk, navigate to "Files" → "File Manager" → "Change Permissions."
If you’re comfortable using the command line, you can fix permissions in bulk via SSH:
find /path/to/wordpress/ -type d -exec chmod 755 {} \; find /path/to/wordpress/ -type f -exec chmod 644 {} \; chmod 600 wp-config.php Important: Never set permissions to 777, even temporarily. This makes your site vulnerable to hackers. If the correct permissions don’t resolve the issue, contact your hosting provider for assistance.
Repair the WordPress Database
A corrupted database can also lead to white screens, especially if you’ve experienced server crashes, plugin conflicts, or incomplete updates. Luckily, WordPress includes a built-in repair tool to fix database issues.
To enable it, add the following line to your wp-config.php file, just before the "That’s all, stop editing!" comment:
define('WP_ALLOW_REPAIR', true); Then, visit yoursite.com/wp-admin/maint/repair.php in your browser. You’ll see two options: "Repair Database" and "Repair and Optimize Database."
- Start with "Repair Database" to fix corruption without altering the database structure. This process typically takes a couple of minutes and provides a detailed report of the repairs.
- If the issue persists, try "Repair and Optimize Database", which not only repairs corruption but also improves database performance. Be aware that this option takes longer and temporarily locks the database.
Advanced users can also use phpMyAdmin for more control. Access phpMyAdmin through your hosting control panel, select your WordPress database, and use the "Check table" and "Repair table" options for any problematic tables.
Reminder: After completing repairs, remove the WP_ALLOW_REPAIR line from your wp-config.php file. Leaving it active poses a security risk since anyone can access the repair tool without logging in.
Update WordPress, Themes, and Plugins
After fixing coding and permission issues, make sure all your site’s software is up to date. Outdated WordPress versions, themes, or plugins can cause white screens due to compatibility problems.
Start by updating WordPress core. If you can access your dashboard, go to "Dashboard" → "Updates" and click "Update Now." If you need to update manually, download the latest WordPress version, extract it, and upload all files except wp-config.php and the /wp-content/ folder via FTP.
Next, update your plugins. In your dashboard, go to "Plugins" → "Installed Plugins" and update them one at a time. Outdated plugins are a frequent source of conflicts, so test your site after each update.
For themes, be cautious if you’ve customized theme files. Updates will overwrite any direct modifications. To avoid losing changes, use a child theme or document your customizations before updating. If you can’t update via the dashboard, use FTP to upload the latest theme version.
Finally, ensure your PHP version is compatible with your WordPress installation. WordPress 6.4 requires at least PHP 7.4, while many plugins recommend PHP 8.0 or higher. Check your hosting control panel to update PHP settings if needed.
After completing all updates, thoroughly test your site. Check key pages, forms, and other functionality. If new issues arise, deactivate recently updated components to isolate the problem.
