You can figure this out by enabling debug mode in WordPress:
- Login to an FTP client of your choice or our web based file manager (found in the client area and control panel).
- Navigate to your website folder (which is
htdocs for your first domain and example.com/htdocs for addon domains and subdomains).
- Open the file
wp-config.php and find the line which contains WP_DEBUG. On that line, replace false with true and save the file.
- Refresh the page on your website and you should now see error messages.
