HTTPS switches to HTTP

[Three Sisters]

Well my host and I are not figuring this out. So far, he says the folders are symlinked. Now he wants me to look for this:

"It would be Global setting, configuration or something to that effect, I apologize but my mind is not recalling exactly where it is on the panel or it's exact name, but I do know it has 'Global' in it. What we are looking to do is find the option to assume https for all pages."

Any idea where it is or what he's talking about?

It's me again. BlueHost and I worked on this all day - to no avail. They confirmed that the folders are symlinked and looked for that "Global https" switch he was talking about. We got nowhere.

If I manually add the "s" to the address, it works. (Although the padlock is grey because of non-encrypted images, I assume.) My host says something goes wrong between the request for login.php? and the page that actually shows up as login.html.

Any thoughts please?
