20230510-1845. Oh, okay! Now I saw what I did!
When I went to change my account/username/login, I created a SEPARATE stand-along WordPress blog! And so my former/PRIMARY site containing all my OLD imported past blogs were retained under the OLD account/username/login.
So while I can NO longer log into the OLD account/username/login, I still can login using my exisiting email address and NEW account/username/login.
This is why I-AM slow! I would rant and rave and complain and whine to myself aloud and loud enough for the crazy neighbor NextDoor to hear and come outta of her house (powned by the bank, of course) and to the WordPress support/Happiness Engineers who are probably giggling. Huh.
My OLD brain cells are both happy and frustrated AND are slower than ever: thusly so, creating a bubble of confusion when NEW stuff baffles creators or users like me!
End of blogging.
Hello Flynn, nice, and good luck!
