I seem to get regularly logged out of my instance for no apparent reason, particularly when I visit another hub (i.e. every time I visit the Hubzilla Support Forum I find myself logged out when I return to my own hub). But it doesn't seem to be limited to this, sometimes I just randomly get knocked out even when I stay on my own server.
Checking off "remember me" seems to have no effect. Is there an Apache or PHP related configuration regarding cookies and/or sessions that I should be looking at?
