Yeah i did that before and like I said WC Vendors pro was the problem. Now it seem to be working fine but tha attributes field is off I try to use an attribute when entering a product and the screen freezes on that tab.
Bsically when I am in the back end admin area when pro is installed I am unable to edit product details suck as price or anything in the product data field. When i just have the free version i am amble to.
