Quote from user: 

I have to sign practically every time visit (even if i leave my browser open on my phone, when I come back I have to sign in again), to the point it puts me off visitng the site sometimes just because. Not helped that I use 4 different devices & 3 browsers. Not every browser seems to remember and apply the login automatically

I'm new to all this but from reading the forums I think it's something to do with my Cron Job logging people out after 30 minutes.
Would it be possible (or advisable) to change the 30 minute value to a larger value? Say 4 hours.
I realize this will give me slightly out timings on the 'Online now' activity but I think thats something I can live with.
I think I've found the right place to edit this (although I could be well off the mark!)

ow_system_plugins/base/bol/user_service.php

Am I in the right place?

Should this be something I'm doing?

Is my users '3 different browser' issue just something he's gonna have to live with?

Not sure how to proceed - any help appreciated!

Cheers

Richard
