Thanks, Eli. I originally tried 1) renaming the gotmls directory and then 2) deleting the directory outright but was unsuccessful. I then turned to my host’s IT people for help. Following your instructions they deleted the gotmls directory and – lo and behold – it worked! So why did it work for them and not me?
Turns out there was a second Word Press installation on the server that I didn’t know about so while I THOUGHT I was renaming/deleting the correct gotmls directory, I really wasn’t. I’m not sure how the second installation happened exactly (I believe it occurred when I migrated the site over from my old host), but whatever the case was, everything works now and I am no longer locked out!
Thanks for being so responsive and thorough in effort to help me, Eli. YOU’RE A LIFE SAVER!
