Cart links redirect back to homepage

Hello,

I am having a slight problem with my shop. clicking "add to cart" on any product and all interaction with shopping cart links (delete item, change quantity) redirects you back to the homepage of the site. This started after I upgraded to 2.1.0. The "proceed to checkout" link works fine, and the items stay in the cart when you return back to the shop, but almost all interaction with the shopping cart returns you back to our homepage. I have the shop offline at the moment, and will I will turn it back on when I can get some assistance.

Also, I have the "Always stay on the same page" option checked in the Cart options on the backend, and it still redirects. Help!
