My add to cart button is not working...

[catttdaddy]

I have seen a few posts on this but none are exactly my issue. First when I click add to cart on a product, I get the popup "continue Shopping 0" nothing is added to the cart. I have changed my template  to the default "Atomic" and disables all external modules. It still does not work. The other posts I have found displayed an error message. Im not getting any errors, it is just not working.

Joomla Vers: 2.5
VirtueMart Vers. 2.6.0

Please advise.
Thank you.
