I am developing a customer support portal using the provided default templates, however since Thursday 17th July I have had multiple of the pages (not all) being uneditable in the design studio because I'm getting an error message saying "Rendering a page with empty content value". If I select "Continue Editing" it simply gets stuck and greyed out. I have tried creating a brand new site with the same template untouched and the same pages are unusable. the templates I get the error with include: Home, Forums, Knowledge Base - Home, My Support, Customer Service - Create Case and Profile.
The website functions perfectly on the desktop preview with all previously mentioned pages displaying fine and without errors.
Any suggestions are much appreciated!
