 * humming bird plugin send this issue “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”

 * Hi [@suruthivenkat](https://wordpress.org/support/users/suruthivenkat/)
 * I hope you’re well today!
 * This is related to gzip compression rather than caching. While Hummingbird is
   supposed to be able to control Gzip compression it still needs webserver to be
   configured properly.
 * The first thing to start with would actually be to do exactly what Hummingbird
   suggests: get in touch with your host and ask them about deflate module and if
   configuration of the server allows controlling it via .htaccess or nginx.conf
   file.
 * If they confirm it then it means it’s a different issue, it may even be a “false
   alarm” but first, please confirm with your host. If it doesn’t solve the issue,
   let us know and also please point us to the site affected so we could check it
   from outside.
 * Kind regards,
    Adam
