Hello,
I found an issue that may be that's related with my other issue with add to cart button in category pages and one page checkout.
You can see this in your demo. For example:
If you click in add to cart button in some product in NSPGK5 in frontpage a popup is showed with this:
The product was added to your cart.
Heimaklettur Men´s Jacket was added to your cart.
and one button left with: CONTINUE SHOPPING and other button right with: SHOW CART
but like you can see button CONTINUE SHOPPING don't go to appropriate category like as assumed, this go to :
index.php/component/virtuemart and show all categories in full page...
I checked this and your demo work fine with FF but have the issue with IE9, also checked this in my website (clean install to test some other things) and this happens in IE9 but also in FF...
Could you take a look to this please, I think that this might have something to do with problem with IE9 and add to cart button in category pages and with One page checkout plugins (with 2 that I tried: from linelab and from cmsmart)
Thanks.
Regards.
