During the ISPConfig setup I chose to use http instead of https. Code: Please select the protocol (http or https (SSL encryption)) to use to access the ISPConfig system: If you want to use your control panel with SSL, select 1. You can then access it under https://www.xyz.de:81. If you want to access it under http://www.xyz.de:81, choose 2. This is just for the access to the ISPConfig cp, correct? The reason I ask is that I have just installed osCommerce using https and I get "page cannot be displayed" when trying to access the shopping cart. To my knowledge, this probably has nothing to do with the ISPConfig setup, but I wanted to make sure. Any further direction is welcome and appreciated. Thanks!
