When you add a product to Aeidahr in your shopping cart

To see the problem

They can not customers to add products to the shopping cart and incoming message the following mis-

“Something” went wrong during your upgrade, knowone else seems to be reporting this problem!

And yes, I attempted to add several products to the cart, nothing would add.
