after updating Cornerstone to the newest version, a few problems appeared. Most importantly, I can't seem to be able to build a new page. Every time I try to work on a new page in Cornerstone a message pops up telling me that the preview could not load due to the iframe response being incomplete and that this is most often related to a plugin conflict, or customizations introducing a PHP error. How can I solve this issue?
The other thing is that I can't use Cornerstone to work on a new blog post. I updated the X theme and enabled the Post settings, so the layout shows the option of using Cornerstone but when I click on it, it just reloads the wordpress site. What am I missing? How can I gain back access to work with Cornerstone on new pages and posts?
Please advise what I could change to make it work again or how I could return back to the older version.
Thank you in advance!
