Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.
If that does not resolve the issue, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).
I’m having issues…..
My backend is completely disabled and we haven’t been able to figure out why. The front end is loading fine. When I rename the theme, the front end goes down too. The default theme isn’t loading. Is there a way to force it or what could be causing it?
