I just upgraded Cornerstone and now the content area is not loading and I’m getting this error.

Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘data’)
at R1e (app.react18.7.4.4.js?ver=7.4.4:134:8337)
at HTMLDocument. (app.react18.7.4.4.js?ver=7.4.4:134:1090

I looked as well and it’s with window.csAppConfig.data though the data looks the same as other sites that are loding with the same version.

I did also move this site from WP Engine to Nexcess hosting

Hi @tristup, I disabled every other plugin and it’s still not working. It’s from upgrading from 5.1.5 to the latest. I have set up a staging site and I’ll provide the login info.

Hi RevCatch,

The issue could be coming from a 3rd party plugin. I would recommend that you start deactivating the Complianz plugin and see how it goes. Perhaps, this thread might interest you:

Kindly let us know how it goes.
