I am using the new Elavon gateway. When I go to checkout to enter the credit card number, the site does NOT transition to https. I believe that it used to transition to SSL when I had the "Manual" gateway selected.
Also, when in the Orders and Payments manager, the site does NOT transition to SSL either. Considering that it is showing my clients CC numbers, I kind of expect that to go to SSL. In fact, the entire admin section could be SSL, but especially Clients, Orders and Payments.
In the Admin / Site page, "SSL Enabled?" is checked.
