This is weird. I had written another post to Debi's Topic of the Day for yesterday. Every time I try to post it, I get the error message and that's actually when all my posting problems began. Today I have been able to post since you helped me DM and was able to post a few 'test' posts, even on yesterday's topic of the day. But when I went back to try to edit my post and add what I had wanted to say, I got the error message again. Then I tried to post a 'test' post. That went through. Then I tried to post what I had wanted to say on the topic of the day and I get the error message again.
I think my post is haunted and I will leave well enough alone.
