When redirecting from a secure site to a nonsecure site, a Security Warning popup will appear.
The Security Warning that you received was: You are about to leave a secure Internet connection. It will be possible for others to view information you send.
This message is a common informational message in Internet Explorer (IE), and can usually be disregarded or disabled.
The first time you use IE, or if you just installed an update or reset the browser to it's defaults, you may see this message while browsing websites that use both Secure and Non-Secure pages. When you enabled your SSL, your users were/are able to move between both non-secure and secure pages as needed. If you receive the above message, don't be alarmed, it is not a NetCommunity specific error, nor does it mean your SSL Certificate is installed incorrectly. The message simply means your browser is switching between non-secure and secure pages, which is a common occurrence within most sites. This message can usually be disregarded or simply disabled.
