Hey Dirk,
Firstly, I believe you’re referring to PHP 8 and not WP 8. The latest version of WP is just 5.8. See the WordPress versions here https://wordpress.org/download/releases/
Thank you for sharing your idea of a feature. We’ll list that as a feature request so it might be taken into consideration for future developments. Just to let you know, there is no feature like that available in most if not all themes and plugins. It could be that it’s currently hard or impossible to implement which is why themes and plugins currently rely on documentation rather than a notification.
Would you mind detailing how we could replicate the issue so we could test it on our sites to confirm that there’s a conflict with PHP 8? This is not a guarantee we could provide a solution though. We’ll just confirm and report to the Essential Grid developers.
I understand your problem and frustration but for now, the only solution for your site is to revert from a backup. You can ask your web host if they can assist you with that assuming they back up your site.
If you don’t have a website backup, please kindly wait for the Essential Grid releases to see if it will fix the issue you described.
Also, it is strongly recommended that you test updates in a staging or test copy of your site. That is a best practice for website owners.
Thank you for understanding.
