Lockdown and problems with common wiki handling
Fragment of a discussion from Extension talk:Lockdown
I have the same problem. I wnat only sysop to delete. I got round it with $wgGroupPermissions['*']['delete'] = true; $wgNamespacePermissionLockdown[NS_MAIN]['delete'] = array( 'sysop' ); Theory being set everyone to delete and then restrict the main namespace back to sysop. You may need to work through the namespaces if you want them restricted. To just bring back delete the first statement may be enough.
