I have made a new Product type, it is called "Product - Dvd" however when ever i goto add a new product on this one Product type i get the yellow box.
I have tried adding a normal product type to that same category and it works without a problem, however when ever i goto add the product type "Product - Dvd" it comes up with the yellow box that say's "Invalid Master Category ID".
I have read a few other topics and cant seem to fix the problem, any ideas ?
