I wanna know how to hide board statistics from Guests if that's not possible, it would be at least helpful if I could mask/hide the total no.of users registered column alone.
I don't think this is possible without a plugin / file edit. However, you can either enable or disable board statistics globally (takes effect on all usergroups)
You can use
Template Conditionals.
After installing that plugin open your index template and perform these modifications.
AdminCP -> Templates & Style -> Templates -> *Theme* -> Index Templates -> index
Find:
{$boardstats}
Replace:
<if $mybb->user['uid'] then>
{$boardstats}
</if>
if you use that plugin then the next code shout be bether
<if $GLOBALS['mybb']->user['usergroup'] != 1 then>
{$boardstats}
<if>
Don't you mean better?
Yes that would be better. I was doing something else at the same time so yeah I just put the code that I knew would work.
