I recently upgraded an X Theme site to 6.1.6 and the theme options menu broke entirely. The only thing I could see was the loading circle icon forever. It never loaded anything, even after 10 minutes.
Then I tried upgrading Cornerstone to the latest release (not sure what license number, but I just downloaded it yesterday on Envato), and then theme options loads but the left panel is completely empty aside from the Save options at the bottom:
Is there a known compatibility issue with the latest releases? I tried clearing all the site cache on the server and through CloudFlare, then reset all cache in multiple browsers. Just looking to figure out what version of cornerstone will with with the latest X Theme build. Thanks
