Safari, FireFox and IE checkout box does not populate, I even tried turning off using Ajax, it WORKS IN CHROME but no other browsers.

Also every time the menu Check Out button is pressed it redirects to:

scentsgourmet.com/liquid-scents/product/listing

Starts off scentsgourmet.com/checkout

and then it goes to scentsgourmet.com/liquid-scents/product/listing

I disable the liquid-scents menu and it redirects to another menu item

ONLY happening in Chrome, why is this happening? Why isn't the cart populating? I am sending whoever respond ASAP a PM with Login To my backend, back up has been created already. Thank you!

I have a party to showcase the website tomorrow and clients interested in taking their business's online and now I have to recommend what? HikaShop with problems? VirtueMart?

ALSO the social Icons are not spacing between Add to cart and the Social Icons.
