That’s strange. Can you access the errorlog of your website? Normally errorlog is in the public_html folder of your server. If you can access it, please open it and send us the error code you see.
If you cannot find a errorlog on your webserver you can enable the WordPress debug log via a plugin like WP Debugging.
To access the WordPress debug.log please follow the steps below.
- Install the WP Debugging plugin and activate it.
- Go to the customizer screen of your website. Appearance > Customize. ( Since this is where you see the error, you need to visit that page again to log the errors into the debug.log file. )
- Then you need to go the wp-content folder of your website via a FTP client program like FileZilla or via the file manager of your web hosting platform.
- Download the debug.log
Then open that debug.log via any text editor and send me the error code you see. Or simply send the debug.log to [email protected].
Thank you
