Testing out my store I found I can't check out and add to cart. When I click add to cart, it just sits static. I've posted this concern on this website but in a different forum (please check this out --> http://forum.virtuemart.net/index.php?topic=38705.0). I posted it here since the version I'm using (as you will see when you click the link) is a "development" version. Please let me know your thoughts.
I was having the same problem.
But I had added some javascript calls to the <head> tag of my template and that was causing the issue. Once I commented out the javascript calls the Add To Cart Button started to work!
