I guess you'd best run a maintenance script; something like
namespaceDupes.php

Onderwerp: [Mediawiki-l] page appears in both NS_MAIN and NS_PROJECT
On
http://radioscanningtw.wikia.com/wiki/Special:Allpages do you see the
page台描:頻率間隔 ?
Well, this is a rare case of a page that was created with a prefix that
would later match NS_PROJECT.
I.e., not waiting for them to change $wgSitename first, I created that page
as if it was already in that namespace anyway.
Now no matter how much I delete it, I can't get it out of Special:Allpages.
