I'm a new user to DNN - Our company has DNN Enterprise Edition installed for our company website. Two months ago, they had a security certificate added to the website,and ever since there has been numerous issues with users being logged out without notification. For example, if you navigate from a non-secure page to a secure page when logged in, then back to a non-secure page, the system will log you out. The user has to log in again. This also happens between non-secure pages too.

I have double, triple checked the page permissions and there is no consistent reason why this is happening. The only other idea is that the system is viewing pages that have a absolute link coded (to access an anchor in a module from another page), and is not carrying over the session information, thus logging out the user. 

 Any ideas?

Yep, http is a different "site" than https. I'm with Richard, consider going all SSL. Also, since you're a Enterprise customer, you could open a support ticket with DNN for help and advice on SSL config.
