FCK 2.5 Disabled Connectors

I thought I had left this problem behind me a few versions back!

<Connector>
<Error number="1" text="This connector is disabled. Please check the "editor/filemanager/connectors/php/config.php" file"/>
</Connector>

// SECURITY: You must explicitelly enable this "connector". (Set it to "true").
// WARNING: don't just set "ConfigIsEnabled = true", you must be sure that only
// authenticated users can access this file or use some kind of session checking.
$Config['Enabled'] = true ;

Is there something else I need to do? Evidently... I'm using PHP, not a cache problem...IE and Firefox

Thanks
