First, sorry raincoaster but I am a RANK novice and I couldn't find this thread when I left the question in the other thread. I apologize--I didn't even realize that you were talking to me!
I know the typo is here, but it wasn't there. If there is a typo in the feed address (which I had at one point when I was trying to do this), it won't verify the address, so at least it doesn't let you make that dumb mistake. When I corrected the typo, then it allowed me to proceed--so the typo in the feed address wasn't a problem.
I am taking your advice given on the other thread and leaving it for 24 hours--I will see if that works. I actually set up another blog--testsilence--and am testing the feed on that one. See, I'm afraid that if people subscribe to the real one and it's not working that they won't come back, so I'm not messing with that right now. I feel terribly alone out there in Word Press. THANK YOU SO MUCH FOR YOUR TIME AND HELP!
Thank you for your patience and your help.
