GZIP Compression error using Hummingbird

I recently uninstalled W3 Total Cache and went to Hummingbird. Got everything working but GZIP, 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
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.
