gZip compression on https (SSL) site not working


I am having problems with my site running slow and am working through the recommendations as per the Hummingbird tests. Today I received this notification:

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.

I contacted my domain host and they have informed me that Apache is enabled and gZip is working on my site, however as my site has an SSL certificate and I am hosted with a shared host that the GZip will not work as it would create security issues for my site.

Can someone please get back to me with a workaround for this? My site is receiving a 32/ 100 score and I really want to start marketing, but with a page load speed of 21.2 seconds, it would be a waste of money to start any marketing yet.

I look forward to your response
