After I migrated one of our portals from DNN6 to DNN7.2, I was not able to access Host > Settings page. After doing some digging around I noticed that the link to settings page was trying to access the page using HTTPS and not HTTP. 

For example, in browser the link is:

https://localhost/muportal/Host/HostSettings/tabid...

Where as on the page the link is:

http://localhost/dukeinfo/Host/HostSettings/tabid/...

Somewhere along the page routing, this link got turned into HTTPS. My portal is not intended to have SSL access. Just for kicks I installed a self signed certificate and not page became available to me. No, installing SSL on our production is not an option for me. I am interested in understanding why this link got changed to HTTPS.

Thanks
