Gzip Compression not showing that it's working on CSS or JS

I'm getting the following error: `gzip is not working properly:

- Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)
- Another plugin may be interfering with the configuration
When establishing the gzip portion of Hummingbird. It writes the correct information to my .htaccess and I verified with Siteground that mod_deflate is installed and and enabled on my server.
