When gor.wikipedia was created, MessagesGor.php were missing hence the wiki uses English namespaces and translations as defaults.
MessagesGor.php has been created and merged on the master and wmf.29 and wmf.30 releases of MediaWiki.
gor.wikipedia however refuses to acknowledge the change after a full scap, rebuildmessages.php and the nighty updatel10.
Evidence is that namespaces haven't updated at the time I am writing this: https://gor.wikipedia.org/w/api.php?action=query&meta=siteinfo&siprop=namespaces
See parent/child tasks for further details.
