Thread:Project:Support desk/MediaWiki 1.16.5 security release

Hello. I use MediaWiki on this site: http://www.mobadaten.info. The current version was and is now again 1.16.4 (http://www.mobadaten.info/wiki/Spezial:Version). The Update on the latest security release 1.16.5 worked as ever. But after this upload even the User "WikiSysop" lost some rights or rather was removed from the Admin- and Sysop-Group. You can't create new pages. You can't edit pages in sereval namespaces like the standard namespace. Well, I rolled back.
