What's happening, Abusefilter works fine at the page level. And I have only use the recommended default settings:

$wgGroupPermissions['sysop']['abusefilter-modify'] = true;
$wgGroupPermissions['*']['abusefilter-log-detail'] = true;
$wgGroupPermissions['*']['abusefilter-view'] = true;
$wgGroupPermissions['*']['abusefilter-log'] = true;
$wgGroupPermissions['sysop']['abusefilter-privatedetails'] = true;
$wgGroupPermissions['sysop']['abusefilter-modify-restricted'] = true;
$wgGroupPermissions['sysop']['abusefilter-revert'] = true;

This is likely related to some config setting. Could you please verify that all assignments to $wgGroupPermissions are correct? Or alternatively, could you list those assignments? (Not just for AbuseFilter)
