In the HTML, it's using
<script type="text/javascript" src="/w/index.php?title=MediaWiki:Gadget-mycommon.js&action=raw&ctype=text/javascript?230"></script>
to load gadgets now. But "?230 is completely wrong. It means the value of ctype parameter is "text/javascript?230". It stops gadgets from being loaded. Firefox says:
The resource from this URL is not text: http://zh.wikipedia.org/w/index.php?title=MediaWiki:Gadget-mycommon.js&action=raw&ctype=text/javascript?230
Remove "?230" or change it to "&230" please.
