Trying to confirm an account request I get stuck on an MWException (the wiki is in German but the exception appears in English too). It seems to be an error in the HTML form of real name (case?). Anyway, it doesn't matter if real name is enabled or disabled. I tried to fix that error for hours but I didn't find a solution anywhere so I hope to get help here. My code (MediaWiki as well as extensions) comes from the Wikimedia git repo (Rel 1.28).
Here is the error:
