Add to cart, price update not working

[macat]

I just installed my store using softacuous and a few things aren't working correctly. When I click add to cart, it goes to cart but nothing is added. On product page if I update quantity, the price that would update total isn't even there?? Any ideas, should I just delete and manually install?

OK, figured it out, found another post with same issue and I needed to add www. to my URL, that fixed it.
