Hi, I never did resolve it. Unfortunately I am going to have to take the plugin off my site as it makes the page that I use the block on unaccessible in edit mode. The page health report showed that my site had stopped communicating with www.remarpro.com. As I had to remove the page this message is no longer showing.
The the wording of the email that I received (copied and pasted below). This message indicated that the plugin with the error was WooCommerce, yet the page was not connected to WooCommerce. The only factor on the page was the post grid block. I tried to redo my content on a newly created page but as soon as I added the post grid block I encountered the same problem. There have been problems on other occassions with WooCommerce’s coding interfering with other plugins (Paid Membership Pro) I don’t know if they have solved the issue.
Email, copied and pasted.
`Hi!
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, WooCommerce.
First, visit your website (https://celticearthspirit.co.uk/) and check for any visible issues. Next, visit the page where the error was caught (https://celticearthspirit.co.uk/wp-admin/post.php?post=29566&action=edit&message=4) and check for any visible issues.
Please contact your host for assistance with investigating this issue further.`
Thanks Chris
