Same here… I modified the .htaccess (in my wp site root folder) as suggested. But this tool https://developers.google.com/speed/ (and others like it) say that gzip compression needs to be enabled.
So that .htaccess code for mod_deflate is not working. Does anyone have success with gzip? Please tell us what you did.
That is very odd. It looks like google may be wrong, or many other test sites on the web are wrong (seems unlikely).
I’m using the same gzip code in my .htaccess file that was provided by Quick Cache. In testing, the google link you provided above says gzip IS NOT enabled on my site. But all of these gzip test sites show that gzip IS enabled and the percentage of compression is around 78-79%, :
