By "getting logged off" I mean after I click Submit this order, a page comes up and says "Your session has expired." There is nothing about your order has been successfully submitted. To be honest, I don't know if this is happening with regular customers or not.
I did not try with a real credit card number. I am assuming that it does work, because authorize.net does show that the credit card is being charged. ZenCart does not show any order placed at all.
To transfer to the new server, I did a cPanel backup of the home directory and had it restored on the new server. I then had to have a new dedicated IP address assigned in order for SSL to work.
Did I follow the instructions in article 100? No. Why not? Do you really want to know? The reason is the same as I don't stop to ask for directions when I get lost. Seriously, I didn't realize that special instructions had to be followed as the domain name and paths are the same. The only difference is the dedicated IP.
