Cannot Get Compression Working Correctly

Installed Hummingbird, well all plugins, but HB to optimize a clients WooCommerce site. After checking everything the error advised me to, it is still failing saying it may be another plugin or deflate module is not active. I have checked our server for deflate module and it was not turned on, so turned it on and re ran and still not working. Wanted to see if I could get someones help. Thanks.
