Hummingbird GZIP Compression and Minification

Hummingbird is displaying some issues:

1) GZIP Compression -> It mentions the "Gzip is not working properly:", but looking at the headers I can see gzip is actually working fine and tested it using an external tool shows the GZIP is enabled too.

2) Minification -> When I try enable the Minification, Hummingbird will show or a error on a SSL or simply refresh and still disabled.
