Hummingbird Says GZip is Not Enabled

Hello,

I was trying to configure Hummingbird to speed up load times and such. However, Hummingbird is telling me I need to enabled mod_deflate to get GZip compression working. But I think it is enabled!! And because Hummingbird does not think it is enabled, I do not believe it is configuring things properly to take full advantage of the gzip compression.

To be detailed, this is what Hummingbird is telling me:

<output>
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
</output>

Both of these resources are telling me that gzip IS enabled though:

Any insight as to why Hummingbird is giving these troubles?
