Enfold error – reports through wpordpress

Howdy!

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 your theme, Enfold.

First, visit your website (LINK REMOVED) and check for any
visible issues. Next, visit the page where the error was caught
(LINK REMOVED/wp-admin) 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: YouClickPic Theme (version 1.0)
Current plugin: (version )
PHP version 7.4.11
