Whenever replace.py makes a change to an article, it adds the following text to the very end of the article: <div id="wikia-credits"><br /><br /><small>From [[wikia:c:starwars|Wookieepedia]], a [[wikia:|Wikia]] wiki.</small></div>
You can see a test of this on Wookieepedia, the Star Wars wiki, here: http://starwars.wikia.com/index.php?title=%22Rachet%22_Gramzee&diff=1780117&oldid=1668014
This seems to be related to a MediaWiki upgrade. I've tried it on both my old version of Pywikipedia, and several of the new snapshots, with the same problem occurring. Any help with this would be greatly appreciated.
