Re: the “resolved” topic “how do you access text editor in order to retrieve drafts of a post”, after following all the steps from that helpful post, my revisions list was still missing. I needed to do an extra step to make the “revisions” list appear.
In the edit mode of the post you’re working on, click the screen options drop down menu (up by “howdy…”). There is (another) box to check for “revisions”.
That finally did it for me. Still haven’t fixed the formatting problem that started me on this mess, and my urge to write has been replaced by teeth-grinding technological frustration (I guess you get what you pay for)!
