Fatal error: Class ‘NOOP_Translations’ not found

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).

Thanks James for the reply

But the solution didn’t work i tried both and i even tried renaming wp-includes/pomo/translation.php

I am not finding any solution. If you can please give me some other solution

Thank you.

Well, renaming a core file will just make things worse, definitely don’t do that.

Just to be sure, you tried renaming the /wp-content/plugins/ directory, and the /wp-content/themes/[whichever-your-current-theme-is]/ directory?

If so, then let’s move on to replacing core files.

Try downloading WordPress again, access your server via SFTP or FTP, or a file manager in your hosting account’s control panel, and delete then replace your copies of everything on the server except the wp-config.php file and the /wp-content/ directory with fresh copies from the download. This will effectively replace all of your core files without damaging your content and settings.

Some uploaders tend to be unreliable when overwriting files, so don’t forget to delete the original files before replacing them.
