Problem with "Special:Wantedpages" after adding Custom Namespaces
After I added some custom namespaces and ran the maintenance script mentioned in this article to move existing pages into respective namespaces, almost all of the affected pages show up in the "Wanted Pages" special page. If I click on them it takes me to the edit window with the existing contents of the page. Does someone know what I am missing here?
