I am running Zen Cart for the first time. My host is midPhase and that is where my database is set up. I am using PayPal as my gateway. When I click on the "checkout" button, I am sent to the "Whoops, you session has timed out page." It doesn't matter if I close out, reboot, or whatever. I have tried to reload my login page, but nothing helps. This is a live site and the client is very unhappy. Can anyone help me QUICKLY????? What files do you need?
