Thank you very much for this information.. and to everyone who has shared info on how to resolve this issue. I have spent the past 4 hours or so, going through all your posts and following through with all of your suggestions for fixes.. but unfortunately, after checking and fixing, and repairing absolutely everything suggested in the dozens of posts I found through using your Search function.. I have not been able to resolved this issue.
So, does anyone have any other ideas? And a quick question on top of that.. if I have no choice but to delte all my categories and then re-do them.. that will mean I will have to upload all the photos in my gallery yet again, correct? I really want to avoid that, if possible, as I have over 10,000 images in my gallery
