What Causes the White Screen of Death?

The WSOD can be triggered by several factors, including:

Step-by-Step Solutions to Fix the White Screen of Death

1. Increase Memory Limit

One of the most common causes of the WSOD is a lack of memory. To increase your PHP memory limit:

  1. Edit the wp-config.php file:
    • Access your site via FTP or the file manager in your hosting control panel.
    • Locate the wp-config.php file in the root directory of your WordPress installation.
    • WordPress White Screen :Add the following line of code before the line that says “That’s all, stop editing! Happy blogging.”:

php

define(‘WP_MEMORY_LIMIT’, ‘128M’);

Edit the .htaccess file:

  • In the root directory, locate the .htaccess file.
  • Add the following line at the end of the file:
    php_value memory_limit 128M

Edit the php.ini file (if you have access):

  • Locate your php.ini file.
  • Add or modify the following line

memory_limit = 128M

2. Disable All Plugins

Plugins can often cause conflicts that lead to the WSOD. To identify if a plugin is the issue:

  1. Disable plugins via the WordPress dashboard for WordPress White Screen:
    • If you have access to the dashboard, go to Plugins > Installed Plugins.
    • Select all plugins and choose Deactivate from the bulk actions menu.
  2. Disable plugins via FTP or File Manager:
    • Access your site’s files and navigate to wp-content.
    • Rename the plugins folder to something like plugins_old.
    • Check your site to see if it loads. If it does, a plugin is the culprit.
    To identify the specific plugin causing the issue:
    • Rename the plugins_old folder back to plugins.
    • Rename each plugin folder inside plugins one by one, checking your site each time.

3. Switch to a Default Theme

Themes can also cause WSOD, especially if they are not compatible with the latest version of WordPress.

  1. Switch themes via the WordPress dashboard:
    • If you can access the dashboard, go to Appearance > Themes.
    • Activate a default theme like Twenty Twenty-One.
  2. Switch themes via FTP or File Manager:
    • Access your site’s files and navigate to wp-content/themes.
    • Rename your active theme’s folder to something else.
    • WordPress will automatically revert to a default theme if it’s installed.

4. Enable Debugging

Enabling WordPress debugging can provide error messages that help identify the cause of the WSOD.

  1. Edit the wp-config.php file:
    • Add or modify the following lines

define(‘WP_DEBUG’, true);
define(‘WP_DEBUG_LOG’, true);
define(‘WP_DEBUG_DISPLAY’, false);

  • This will create a debug log (debug.log) in the wp-content directory.

5. Repair Corrupted Files to resolve WordPress White Screen

Corrupted core files can also cause the WSOD.

  1. Re-upload core WordPress files:
    • Download a fresh copy of WordPress from wordpress.org.
    • Extract the files and upload the wp-admin and wp-includes directories to your site via FTP, overwriting the existing directories.

6. Check for Syntax Errors

If you recently edited code on your site, a syntax error could be causing the WSOD.

  1. Review recent code changes:
    • Access your site’s files and review any recent changes to the functions.php file or other custom code WordPress White Screen .
    • Look for missing semicolons, brackets, or other syntax errors.
  2. Restore from backup:
    • If you have a recent backup of your site, restoring it can resolve the issue.

Conclusion

The WordPress White Screen of Death can be daunting, but with systematic troubleshooting, it can be resolved. By increasing the memory limit, disabling plugins, switching themes, enabling debugging, repairing corrupted files, and checking for syntax errors, you can identify and fix the underlying issue, ensuring your site is back online.
