Unable to edit tab text once text had been already entered. There is no issue when the new tab says ‘click to edit’. The issue was with already entered text that I wanted to change. Even when I scrolled back up to the tab (as you advised) when it jumped down to the content, I was unable to edit it.
How to resolve:
A blue box pops up when you try to re-edit a text box have a link address and a link that says ‘change’ or ‘remove’. You have to click the ‘remove’ link and then are able to edit!
