I think one of the marketplace plugin updates messed up the shopping cart

Having a little trouble with the shopping car...not sure if its me or the past updates to marketplace.

The shopping cart appears to no longer work in non-https mode....Not sure why.

I hadn't been testing that since the last few small updates but I noticed now that if I add something to my shopping car.

I am running nginx.

Thanks, this is pretty critical to my set up so an asap fix would be helpful! Thanks
