I have already used Product Tabbed Pro at my website with no problems. Recently I have tried to install it again after reinstalling Zen Cart but unsuccessful.

I have run sql patch and copied the files in CSS, Images, jscript and Templates folders. I’ve also amended product info display page with the codes provided. But my product info page isn’t tabbed but still appears as normal page (no tabbed).

Can someone help me to work out where the problem is?

Many thanks.
