There has been a critical error on your website.



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 tried to resolve, but it doesn’t resolve my issue, still not working.

Is there any way to fix it?



What was done to the site before th iui s problem? Any updates, changes, etc.?

I changed the theme. And I received an email from WordPress a week ago.

Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, Nextend Facebook Connect.

First, visit your website ( and check for any visible issues. Next, visit the page where the error was caught ( and check for any visible issues.

Please contact your host for assistance with investigating this issue further.

If your site appears broken and you can’t access your dashboard normally, WordPress now has a special “recovery mode”. This lets you safely login to your dashboard and investigate further.

To keep your site safe, this link will expire in 1 day. Don’t worry about that, though: a new link will be emailed to you if the error occurs again after it expires.

When seeking help with this issue, you may be asked for some of the following information:
WordPress version 5.5.3
Current theme: Goya Child Theme (version Current plugin: Nextend Facebook Connect (version 2.0.2) PHP version 7.4.13

The error is about this?

I’ve already deleted the file of ‘Nextend Facebook Connect’ plugin in Cpanel. (can not deactivate on wp-admin)
