Users don't have permission to edit their own articles
Users don't have permission to edit their own articles after applying this fix here: http://www.vaultwiki.org/issues/1727/
To clarify, for the user group, "Can Edit Wiki Articles" is set to no.
This means that the edit tab does show up on your own article (and not others) but when clicked get a no permission page.
EDIT---------
ALSO, when I set the global "Can Edit Wiki Articles" to yes, the edit button appears on all pages - but only on articles owned by the user can the user edit. Otherwise the no permission page is printed.
So two issues here:
1. Can Edit Wiki (OFF) - User has no permission to edit even his own article.
2. Can Edit Wiki (ON) - User has no permission to edit articles other than his own.
