When you close the forum

[AMG021]

When i close my forum only admins can see the posts. How can I make it so more USERGROUPS can see the forum?

I Don't know how to fix this code so i could set the usergroups that i want. If someone could figure it out for me thats going to be great

// check that board is active - if not admin, then display error
if (!$vbulletin->options['bbactive'] AND THIS_SCRIPT != 'login')
{
    if (!($vbulletin->userinfo['permissions']['adminpermissions'] & $vbulletin->bf_ugp_adminpermissions['cancontrolpanel']))
    {
        if (THIS_SCRIPT == 'external')
        {
            // don't output HTML for external data
            exit;
        }
        $show['enableforumjump'] = true;
        eval('standard_error("' . str_replace("\'", "'", addslashes($vbulletin->options['bbclosedreason'])) . '");');
        unset($db->shutdownqueries['lastvisit']);
    }
    else
    {
        // show the board disabled warning message so that admins don't leave the board turned off by accident
        eval('$warning = "' . fetch_template('board_inactive_warning') . '";');
        $header = $warning . $header;
        $footer .= $warning;
    }
}

in global.php.
