Users are always logged out on front end Users are always logged out on the front end on my Craft website.  Even when logged in as admin I can access the CMS but on the front end user session always returns the following.

Craft\UserSessionService Object
(
    [_identity:Craft\UserSessionService:private] =&gt; 
    [_identityCookie:Craft\UserSessionService:private] =&gt; 
    [_userModel:Craft\UserSessionService:private] =&gt; 
    [_userRow:Craft\UserSessionService:private] =&gt; 
    [_sessionRestoredFromCookie:Craft\UserSessionService:private] =&gt;

        (
        )

    [behaviors] =&gt; Array

    [_initialized:CApplicationComponent:private] =&gt; 1
    [_e:CComponent:private] =&gt; 
    [_m:CComponent:private] =&gt; 
)


Does anyone have any idea why this could be happening?
I tracked down a similar problem, and documented it here: The Case of the Missing PHP Session

I'm not sure if it'll address the issue you're having specifically, but it may give you some clue on where to look.
