Dear all,
I've upgraded my own MediaWiki and tried to enable Template:Languages functionality to support page translation. The result, however, is not correct: http://taipedia.info/mediawiki/index.php/Template:Languages
The ParserFunctions extension had been installed.
The keywords to search for this question are not easy to acquire to me, therefore I have to bother you guys here. Sorry about that and thanks for all your patience.
Best Regards, Mike
