Ah, the dreaded White Screen of Death (WSOD) on WordPress. Don’t worry, I’ve got you covered. Here are some steps to troubleshoot and fix the issue:

Method 1: Disable Plugins

1. Via WP-Admin: If you can access the WordPress Admin area, go to Plugins > Installed Plugins and deactivate all plugins.
2. Via FTP: If you can’t access the admin area, connect to your server via FTP and navigate to wp-content. Rename the plugins folder to something like plugins_old.

Method 2: Switch to a Default Theme

1. Via WP-Admin: Go to Appearance > Themes and activate a default WordPress theme like Twenty Twenty-One.
2. Via FTP: Navigate to wp-content/themes and rename your current theme’s folder.

Method 3: Increase Memory Limit

Edit your wp-config.php file (usually in the root directory) and add the following line:

define('WP_MEMORY_LIMIT', '64M');

Method 4: Debug Mode

1. Open wp-config.php and find the line that says /* That's all, stop editing! Happy blogging. */.
2. Just above that line, add the following:

   define( 'WP_DEBUG', true );

3. Refresh the page and look for error messages. This might give you a clue about what’s going wrong.

Method 5: Check File Permissions

Incorrect file permissions can also cause WSOD. Use your FTP client to make sure folders are set to 755 or 750 and files are set to 644 or 640.

Method 6: Reupload Core Files

1. Download the latest WordPress version.
2. Unzip it and upload everything except the wp-content folder via FTP.

Method 7: Consult Error Logs

Check your server’s PHP error logs. This might provide clues on what’s breaking the site.

If all else fails, you might need to consult your hosting provider or get professional help. Hope this helps you get back on track! Let me know if you’ve got more questions.
