Thread:Talk:MediaWiki/Users of my Wiki getting kicked while editing but me not

hey so i have a problem. For our office in our university we're running a small mediawiki.

The problem is that users get kicked out while editing their project pages like after 20-30minutes of the editing window being opened.

I did several self tests and i do not get kicked out while having the editor open (even for 4hours). I am admin though.

The session token is on 0 which is default anyway. Is there any other option or user right i am missing?!
