Hello, About a month ago I upgraded to pro for my website, completing the long transition from WP Bakery to Cornerstone and finally to Pro.
I edited a few pages and did a few other things with no problem. However, recently I went to update a critical, time-sensitive page and was met with the error message noted in the title. I tried editing the WP-configure.php file using Filezilla but that did not solve the problem.
Please help
