I cannot do gzip compression. gzip is not working properly.
I have disabled all plugins except Hummingbird to rule out plugin conflict so it must be a server issue:
Your server may not have the "deflate" module enabled (mod_deflate for Apache, ngx_http_gzip_module for NGINX)
I have other sites on the same hosting that have the same issue.
Any tips how to fix this or must I simply contact the hosting company?
