Squirrelmail pluggins not showing up under options after installation

[Zauny]

I have recently installed Squirrelmail and pluggins I have added aren't showing up under options. Everything else works fine but the pluggins. Any ideas on how I can solve this would be greatly appreciated...

I added the plugins manually in the config/config.php

$plugins[0] = 'newplugin';
$plugins[1] = 'newplugin2';
$plugins[2] = 'newplugin3';

not really user why they weren't added when I used the conf.pl for squirrelmail configuration...
