Thread:Talk:MediaWiki/Protection level of MediaWiki/reply (14)

Woah, thanks! But visiting gives me the following error:
 * The page "Template:Main page" cannot be reviewed. No configuration is possible.

I guess this message should be more informative, because I can't figure out whether this is because I lack the proper rights, or because the template namespace is not set up to use flagged revisions, or some other reason...
