From Type historian’s advice, I have installed and activated the two plugins
1) Black Studio TinyMCE Widget
2) Optimize Database after Deleting Revisions
Updated again but still no luck.
The grey banner on the top of the page still appears.
Please advise how to save and get rid of the “edit” mode grey banner at the top of the page.
