I’ve moved my X theme to PRO because I have issues with Cornerstone. Before it worked and suddenly “something” spoiled it and it has not gone well again. I can not get into the editor and I can not find the error. Now with this new theme (PRO) I see that “EDIT WITH PRO” is used but I still have the same bug.
Clicking on EDIT WITH PRO with Internet Explorer 11 stays in the publisher infinitely. Chrome shows you the web but without the left bar to edit content.
The rarest thing is that with version Cornerstone 1.3.3, YES, it works with the theme X in Internet Exprorer but NOT in Chrome.
