我已经安装了WP Super Cache，并且已打开压缩。

然而，两者GIDZipTest 和Google Page Speed Insights Chrome extension表示未启用压缩。

我将以下内容添加到我的。htaccess文件，但他们仍然表示未启用压缩：

AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
