MyBB Community Forums

If you go to...

You can see the hidden forums, such as our mod area called "Seafoam Cave." How do we get rid of them showing there?

I don't see any forum called 'Seefoam Cave'. You can see them because you are an administrator (who has permissions to view the forum) who is viewing the RSS...

We had a regular member report that it was showing, and others have too.

Try this:
Admin CP --> Board Settings --> Change --> Forum Home Options and set "Hide Private Forums" to "Yes".

Or find this in misc.php:

if($perms['canview'] == "yes" || $mybb->settings['hideprivateforums'] == "no")

And replace with:

if($perms['canview'] == "yes")

Thank you! The second method worked. There was no option for the first in the Admin CP.
