I tried to report these to the module bug reporting form but there is no category for CBB and newbb only goes up to version 2.0RC.

I am using XOOPS 2.2.3 on a Debian Sarge system.

If you try to edit an unapproved (anonymous) post from the admin menu you get this error:

Fatal error: Call to undefined function: newbb_adminmenu() in /var/www/html/modules/newbb/admin/index.php on line 102

from this url:

/modules/newbb/admin/index.php?op=mod&post_id=xxx

It is useful for the administrator to edit unapproved posts before approving.

Try posting the bug over here -> http://cbb.getituponline.com/

Your bug will get seen by the right people for sure.
