Cornerstone is no longer loading and only displays a solid gray screen.

Browser console consistently shows:

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'data')

app.react18.7.9.2.js?ver=7.9.2:149

We have already tested:

  • Chrome and Safari — same issue
  • LiteSpeed Cache disabled — same issue
  • WPML and MalCare disabled for conflict testing — same issue
  • PHP 8.4 and PHP 8.3 — same issue
  • PHP memory limit: 512M
  • PHP time limit: 300
  • PHP max input variables: 10,000
  • PHP post/upload limit: 100M

Cornerstone version appears to be 7.9.2.

Could you please investigate what is causing Cornerstone to fail during initialization? The problem began approximately one week ago.

Hello @ywoolf,

Thanks for writing to us.

I checked your website, and it appears that the issue may be related to caching. I purged all the cache from the LiteSpeed Cache plugin and temporarily deactivated it. The page builder is now working correctly. Please clear your browser cache and check it again. I tested it in Google Chrome version 151.0.7922.170.

Thanks

Hello @ywoolf,

I rechecked your website, and the page builder is working correctly on my end. I tested it using Google Chrome version 151.0.7922.170. I suggest testing it in a different browser or on another device. Please also ensure that no browser extensions are blocking JavaScript or CSS files from loading. For reference, please review the screen-recording video.

Thanks
