(I'm by no means an expert but...) I don't know if anybody else had this problem but it happened to me twice with 2 different autoblogs, I used wp_insert to manage my ads which worked very well at first but after I got about 200 post up I couldn't change ANY of the setting under "manage ads"... hell the page didn't even load properly... my advice is just to avoid wp_insert and use another plugin... it could save you some time if you want to experiment with different ad setups.
