gzip compression using Hummingbird

Hi, I tried activating gzip compression on my site using Hummingbird and I am getting this error, so just raising a ticket as suggested.

=== error 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)

– Another plugin may be interfering with the configuration

If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.

=== end of error ===

my site runs on a shared web hosting that uses Apache
