6.7.0 Beta 3 - Broken Cornerstone

Support
#1

Hi Charlie,

I have a site which appears to be broken with Beta 3. All of the various buttons throw errors (Dev Tools, Code area, parameters, etc.). All give the Uh Oh! message. Inspecting the pages, I get the below:

Uncaught TypeError: Cannot read properties of undefined (reading 'tcoIndex')

Hello @whitemedia,

Thanks for reaching out.

The builder seems to be loading correctly on our end, and we haven’t encountered any errors while working with the interface. Are you still experiencing the issue? If yes, please try to clear your cache or test it in a different browser.

Hi @Ismael,

I am still getting the issue on this one website others seem fine.

This is a development website, so no website cache in in place. I have tried:

  • Clearing all browser caches.
  • Trying in Chrome
  • Trying in Chrome Incognito
  • Trying in Edge
  • Trying in Edge InPrivate
  • Rebooting the computer

The same behaviour happens in all, as per the screenshots below.

This was an issue with CSAI, I released a fix in CSAI beta2. I updated this on your site and you should be good now. Thanks for sending this our way.

Thanks Charlie, but this has started reappearing with Beta 3 (currently installed).

Sorry - just seen our messages have crossed over - all looks good again! Thank you.
