cart blocked with a product

Dear,

Something very strange is happened to the cart of this subsite:

http://www.pixshopping.com/biolaloustore/

Is this maybe a virus???

I add two products to the mini cart. (see screenshot attached)

The products are correct but the total is wrong.

When I go to see the cart I can't find the product I have added before.

Also the prices and the total are different.

Please see the screenshots attached.

try yourself. support access is open.

thanks for a quick reply.

Paddy
