Gzip compression not working fully


I’m trying to enable gzip compression with Hummingbird, but I’m running into some problems.

Gzip compression for HTML files has been enabled succesfullt but javascript and CSS won’t.

I’ve contacted and we’ve walked through some steps that might have cause the issue but to no avail. The deflate module has been enabled (you can check here) and the code entered into my .htaccess and even an extra line of code into my user.ini as well, but can’t get the compressoin of Javascript and CSS to work.

Do you have any tips?
