Hi,
A site I manage had a critical error this morning after updating the Kadence Blocks – Gutenberg Page Builder Toolkit plugin.
Only the home page was affected (page id noted in the details below). I could still access the Dashboard and other pages. I was able to revert to a backup of the site from a few hours previous, so for now the page is back and the site is ok, but I can’t update the plugin again until I know that crash won’t happen again – and won’t happen on other sites I manage as well.
WP Admin sent an email notification, with specific details of the error:
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 one of your plugins, Gutenberg Blocks by Kadence Blocks – Page Builder Features.

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 5.4.2
Current theme: Ascend – Premium (version 1.9.12)
Current plugin: Gutenberg Blocks by Kadence Blocks – Page Builder Features (version 1.8.6)
PHP version 7.3.19
