Manual:$wgAlwaysUseTidy/zh

详情
In some internal places in MediaWiki (mainly when generating parts of the interface), HTML Tidy is not used by default, even when $wgUseTidy is turned on. If you want to override this, and always use HTML Tidy for every bit of wikitext parsing, you can set this option to true.

您并不清楚进行该操作的原因；您的服务器性能不理想. 但是如果MediaWiki继续生成错误的HTML代码甚至当$wgUseTidy处于启用状态时，您值得考虑采用快速修复等方法来快速解决问题.
