Step-by-Step Solutions

1. Disable All Plugins

   A plugin may be causing a fatal error. Disable them all to see if the site loads. If it does, reactivate one by one to find the culprit.

   wp plugin deactivate --all
2. Switch to Default Theme

   A theme bug can trigger a critical error. Activate a default WordPress theme to test.

   wp theme activate twentytwentyone
3. Update WordPress Core

   Outdated core files may contain bugs. Updating ensures you have the latest fixes.

   wp core update
4. Increase PHP Memory Limit

   Low memory can cause fatal errors. Add a memory limit in wp-config.php.

   define('WP_MEMORY_LIMIT', '256M');
5. Repair .htaccess

   A corrupted .htaccess can block WordPress. Delete it and let WordPress regenerate a clean file.

   rm .htaccess
6. Check Database Integrity

   Corrupted tables can cause critical errors. Run a database check and repair if needed.

   wp db check
