Thread:Project:Support desk/Groups in protect page not being displayed

Hello everyone. I am trying to protect a page to edition to allow only users from a determinated group to edit. I already added the group permission:

$wgGroupPermissions['*']['edit'] = false; $wgGroupPermissions['Dev']['edit'] = true; $wgGroupPermissions['Infra']['edit'] = true; $wgGroupPermissions['Interface']['editinterface'] = true; $wgGroupPermissions['Test']['edit'] = true; $wgGroupPermissions['Viewer']['read'] = true; but they are not showing there, the only ones that i can select are: Allow all users Block new and unregistered users Administrator only How can I change that?
