i'm going to have a problem with this product, i've installed it on a fresh vbulletin 4.1.7 board..everything work well but when i go to make a review of a product i obtain a white page after pressing "post review" button.
any idea on why i've this problem?
also, and this is problably a noob question

, i don't understand how a user can post a new product; i've put on yes the "Allow Members to Post Products" option on the ACP but i can't figure out where is the form or any link for add a product using the front end.
thank you!
