I have tested the wiki code in Github. https://github.com/openSUSE/wiki However, the wiki require some config files that are not included in this repo. I clone the latest code and install it on my computer. This is the screenshot: http://imgur.com/5nSxncV Header tags show the correct names, not "disable". The file /srv/settings/wiki_settings.php is included in LocalSettings.php. I am afraid that this file contains some specific configuration for Chinese wiki instance. If the system administors can send me this file, without database information and secrect key, I can analyse it and find the problem. And, the "bento" skin is really a mess, generating invalid HTML. http://imgur.com/B1Jxn8H
