SVGZ format only works when I test it on local on Google Chrome. (doesn't work on other browers) It worked fine with svg though. Otherwise, on server, it doesn't work. I tried to add a .htaccess file with the lines
AddType image/svg+xml svg
AddType image/svg+xml svgz
AddEncoding x-gzip .svgz
But it still doesn't work. Tried it inline and background, same result.
I tried it in multiple background (with texture), and on the bottom of the page in inline.
I'm stuck.
