Product specification not appearing

Hi, I recently downloaded nopCommerce & configuring it. My client doesn't want to have the Product reviews feature. Hence I disabled it from admin console. But now in the product details page, I don't get the Product specifications tab also. Am I missing something else? Please guide me.

What version are you using?

I am using version 1.5
I was trying out different customizations by changing the configuration at the admin section as well as changing the code; eventually figured out the product specs tab missing. I am not able to figure out which change actually caused it. However I downloaded version 1.5 again and using it.
