Content Issue, CS not loading at all and gray screen

Hello Themeco Support,

We recently experienced a major issue where all content inside Cornerstone was completely removed in the middle of the night, and all pages were gone. We had to restore an older backup of the website in order to get the site working again and recover all of the content.

Since restoring the backup, Cornerstone is no longer functioning properly. Whenever we try to open Cornerstone, we only get a gray screen and the builder does not load.

To troubleshoot the issue, I have already tried the following:

  • Disabled and reactivated the child theme
  • Disabled and reactivated all plugins
  • Manually updated both the theme and the Cornerstone plugin
  • Checked the allocated PHP memory limit (512M)

Unfortunately, none of these steps resolved the problem, and Cornerstone still only shows a gray screen when opening with nothing accesible.

Could you please help us identify the cause of this issue and advise on the next steps?

Thank you in advance.
