Ancart issues

Hi,

I am using ancart template. the reviews tab is missing from the product page

How do I solve this?

Also, I have a tried a lot to add social media extensions but none of them seems to work. Please help me

What did the theme author have to say about the missing tab? He knows what is inside the theme itself.
