When deleting pages in the WiktionaryZ namespace (i.e. relational data) on several occasions I have observed that the page does not really get deleted. It can still be seen in Special/Allpages, and most obviously the link to the page is still blue in the log over deleted pages (Special:Log/delete). However, repeating the deletion request does remove the page completely. All the pages where I have observed this behaviour are pages containing more than one language, namely both English and English (US), pages which I have previously disconnected from any DM, so that the only information available is the language names. The error is easily reproducible by disconnecting all Languages on a given page (that has more than one Language - note, I have only tested on English/English (US)!) from any DM:s, then try to delete them using the top tab. Examples of words that I have observed this behaviour on: WiktionaryZ:reproduction (biological), WiktionaryZ:stock (trade), WiktionaryZ:substitutability (chemistry)
This has been solved some time ago (maybe by the update of Mediawiki, but not sure). Also, I have changed the software so that the page is created only once, even when there are several languages.
