Thread:Project:Support desk/Bundled extensions BreadCrumbs and InterWiki not working./reply

I have not checked your errors in detail, but they are most likely caused by this: The releases from last week contain the wrong extensions. The version, which is included, is not the one from the according branches, but it is some snapshot from the master branch. This breaks systems. Until this gets fixed (probably with the next release by the end of this month) you can use the extensions, which come with MediaWiki 1.22.2 instead.
