Error with page

[velourfilm]

Hi

There seems to be an error within the latest update for Formota where we can’t access any page in the Dashboard anymore and instead just gets this error message: “There has been a critical error on this website. Please check your site admin email inbox for instructions.”

Wordpress then sent us an email where it says:

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, Slider Revolution.

First, visit your website (https://www.velourfilm.se/web2020/) and check for any visible issues. Next, visit the page where the error was caught (https://www.velourfilm.se/web2020/web2020/wp-admin/post.php?post=1780&action=edit) 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 5.8.3
Current theme: Formota – Child (version 1.0.0)
Current plugin: Slider Revolution (version 6.2.23)
PHP version 8.0.16

Is this anything you can help us with??
There are no visible errors on the site – only when you try to edit it via the Dashboard.

Kind Regards Velourfilm AB
