Cornerstone Elements tool was working before, no new plugin was added to the site. This is what happen when I try to edit a post in Cornerstone today. I want to add an image element, I click on the element icon on the left panel, than the elements icon, CSS and JS disappear. I reload the page, it come back. I click on it and it is disappear again. The cornerstone is latest version. All wordpress and theme are uptodate. I use integrity and theme x. I did cleared Style Cache.
