Auto-logging out/auto time out issue

[XYZ500]

I started a new vB forum. Users are complaining about an issue that they get autologged out after sometime of inactivity. Like 15-20 mins of inactivity. I tried to notice this issue with my own account and it seems to have the same problem.

What could be causing this and how to fix it? It is getting annoying for my users to have to login again and again.

Ask them to select "Remember Me?" while they log in. Or have this check box selected by editing the header template.

Or install this mod, https://vborg.vbsupport.ru/showthread.php?t=256090 which will auto tick the Remember Me box.

Can I have anyway to make the Remember me box auto ticked without any plugin needed? I mean in the template only.

Find in header template:
<label for="cb_cookieuser_navbar"><input type="checkbox" name="cookieuser" value="1" id="cb_cookieuser_navbar" class="cb_cookieuser_navbar" accesskey="c" tabindex="103" /> {vb:rawphrase remember_me}</label>

Replace it with:
<label for="cb_cookieuser_navbar"><input checked="checked" type="checkbox" name="cookieuser" value="1" id="cb_cookieuser_navbar" class="cb_cookieuser_navbar" accesskey="c" tabindex="103" /> {vb:rawphrase remember_me}</label>

Edit: Seven SKins beat me to it, but I thought I'd mention that I believe the reason it isn' checked by default in the first place is that members shouldn't use "remember me" if they aren't on their own computer.
