The WordPress White Screen of Death (WSOD) is a common error that results in a blank screen, making it difficult to understand the cause because there are no error messages displayed. It can be caused by plugin or theme conflicts, exhausted PHP memory limits, or issues with the WordPress core. Here’s a step-by-step guide to troubleshoot and fix the WSOD:
Enable Debugging
Enabling the WordPress debug mode can help you uncover any specific error messages. To do this:
- Access your site via FTP or your host’s file manager and locate the
wp-config.php
datoteka. - Edit the file and look for the line that says
define('WP_DEBUG', false);
. Changefalse
totrue
. If the line doesn’t exist, add it above the “That’s all, stop editing! Happy publishing” line:
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
This configuration will log errors to a file named debug.log
within the wp-content
directory without displaying them to your site’s visitors.
Deaktiviranje vseh vtičnikov
Plugins are often the culprit behind the WSOD. To check if a plugin is causing the issue:
- Use FTP or your host’s file manager to navigate to the
wp-content
folder. - Rename the
vtičniki
folder to something likeplugins_old
. S tem deaktivirate vse vtičnike. - Check your site again. If it’s back up, one of the plugins is causing the problem. Rename the folder back to
vtičniki
and then deactivate each plugin one by one in the WordPress dashboard to isolate the problematic one.
Increase PHP Memory Limit
Insufficient memory allocated to PHP can also lead to the WSOD:
- V
wp-config.php
file, add the following line:
define('WP_MEMORY_LIMIT', '256M');
This increases the PHP memory limit to 256MB. If you still encounter the WSOD after this, the issue might be related to your hosting environment’s overall memory limit, and you may need to contact your hosting provider.
Check for Syntax Errors
If you recently edited any files, a syntax error could be the cause:
- Review the changes you made. If you’re unsure, revert to a previous version of the file.
- Use a PHP syntax checker or editor with syntax highlighting to spot and correct errors.
Clear the Cache
Sometimes, your browser or caching plugins can show a cached version of the WSOD:
- Clear your browser cache and, if possible, clear the cache via your hosting control panel or caching plugin settings.
Preverite dovoljenja za datoteke
Incorrect file permissions can also cause the WSOD:
- Files should be set to 644 or 640, and directories to 755 or 750. You can check and change permissions using an FTP client.
Restore from a Backup
If none of the above steps work, restoring your site from a backup can be a quick solution to get your site running again:
- Use a recent backup to restore both your WordPress files and database.

If you’re still stuck, your hosting provider can offer insights into server errors, database issues, or other hosting-related problems that might be causing the WSOD.
By methodically following these steps, you should be able to diagnose and fix the cause of the WordPress White Screen of Death. Remember, making regular backups and testing changes in a staging environment can help prevent issues from affecting your live site.
