Trying to set up payments, shopping cart and user info

Hi there,
I'm trying to finish setting up taking payments and registering users for my yoga classes etc in events + with marketplace plug in for products. I can place items in the shopping cart but then it disappears. I have the plug in in a widget that the problem?
Also want to make sure full customer info is stored when they book an appt, I've disabled social sign ins so I could do that. Also downloaded membership plug in if that helps.

I need everything to work by tomorrow as we are launching our! :slight_smile:
