When I updated to the latest version of Cornerstone, I got the following critical error message. I then restored my site to when Cornerstone was functioning, and when I go to edit a page, it just turns grey. I spent a lot of time troubleshooting and have had no luck, so I just added six months of additional support. Please help.
WordPress version 6.4.3
Active theme: Flatsome Child Theme (version 3.5.3) Current plugin: Cornerstone (version 7.4.11) PHP version 7.2.12-1+ubuntu18.04.1+deb.sury.org+1
