Hi Chuck, strange problem here
You can see that there are 13 pictures in category "1000", 28 pictures in category "1003" and 6 pictures in the category "1006". Problem is, that only the pictures in category 1003 are showing; when a user tries to view the pictures in category 1000 or 1006 photopost says that there are no pictures available. There is no approval queue for those categories and nothing has to be confirmed from an admin. Recently I have disabled the upload in these categories for regular users - only admins still can upload pictures (as these are photo categories of the past year). Anyway, viewing of photos in this categories is still possible. Strange problem, isn't it?
Best Regards from Austria, Chris
