It’s fixed! The lovely Alex G. on staff at WordPress started off his note to me by promising not to eat me, as per my concern in the last post. He then informed me that the problem was with an image in one of my articles which had an errant “/” within its coding. Something that I, in a million years, would not have suspected. He fixed it for me, and voila! Problem solved.
The moral of the story: if you have a problem, go to support and/or post about it. And don’t be afraid – WordPress doesn’t eat bloggers. At least Alex G. doesn’t.
