Thanks, after saving the permalink even if it was already set as expected, it “refreshed” and enable the expected behavior.
CloudFlare do not combine, it “just” minify.
So I decided to use the W3 Total Cache minification + combine option.
– Do not use both, so unselect Minify in the Cloudflare WP Plugin
– Do not use generic CDN when the ClouldFlare (with W3 TC extension) is used.
Result is good so fare.
same issue for me. Any news, or more detailed info to solve it ?
