I followed one of the suggestions--which was to click the "revert widget templates to default" button in the layout settings using html. I have no idea what that means or what it did or if it helped. I'm just glad I could finally find it! It would be very helpful to me if you would try again to comment. If it doesn't work would you email me so that I can contact "help" again to see if they have any other solutions?
The only other thing I know to suggest is to keep trying. Maybe it has to do with the traffic on Blogger at a certain time, or if I am adding a post. I feel as if I have learned a lot since I started blogging, but most of what I've learned just shows me how much I don't have a clue about how all this works!
