I have been trying to update to X 5.x for several months now along the way to update to Pro. However, every time I have attempted the update to X 5, all of the text fields on my site do not display either in the Cornerstone editor or on the live pages. I even add a new text field and it does not display either in the editor or in the live page. Interesting enough, the any text in a classic block quote does display correctly. There are other issues as well such as all accordions not displaying any text. Also the text on tab headers does not display.
I originally thought SiteGround might be the problem as there seem to be many issues there. So I ported the entire site to a testing are on Ace Host, then did the upgrade to X 5.2.2 and all of the issues remain.
Running X 5.2.2, Cornerstone 2.1.3, Wordpress 4.8.2
I have tried to the normal fixes of deactivating all plugins to see if one was causing a conflict and removing all custom CSS. Even with no plugins (except Cornerstone) and zero custom CSS, the issue continues.
I would really appreciate your help in resolving this issue so I can finally update the site from X 4.6.4 to Pro.
