In Hummingbird -> Gzip Compression I see this message.
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.
I contact with host and they say:
- Gzip compression works fine on all our servers. - Two php modules/extensions are turned on by default on our shared servers, which is going to allow both gzip compression and deflate header requests from the browser when the content is requested.
Host also try rules for .htaccess file.
Issue still exist.
The shared servers use nginx and apache.
