Site Auto-Logout question
 

The site logs me out randomly, sometimes after only a moment or two and sometimes not at all.

Furthermore, at random times, when it makes me re-login, it will clear every new post as though I've read them.

I've been working around this but it's a bit of a nuisance. I can't find any settings to change how long I stay logged in & I'm wondering if there's any remedy out there.
