[Mediawiki-l] uploads permissions

[André Meunier]

Hello,

I've enabled uploading, and it works for me (as sysop), but other users 
can't upload file. When uploading it gives me the namespaceprotected 
error message.
Which namespace is dedicated to the files uploaded?
I've tried setting the $wgGroupPermissions['*']['upload']          = true;
I've tried making a new group 
$wgGroupPermissions['uploadaccess']['upload'] = true;
and still it gives me the error message for the namespaceprotected.
