I have 2 dedicated servers. One some sites Hummingbird agrees with gzip, on other sites do not agree.
This is the error I see.
All file types have "Inactive"
Gzip is not working properly: - Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX). - Contact your host. If deflate is enabled, ask why all .htaccess or nginx.conf compression rules are not being applied. If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.
