Hi !
I would like to know the best practice for minifying my wordpress scripts conjuging Cloudflare and 2 plugins (W3 Total Cache & autoptimize) to keep the best performance.
I suggest you just pick one…the one you like most. Personally, I use Cloudflare’s Auto Minify instead of my Wordpress cache plugin’s option. I do this because I don’t like to alter my WordPress output until the very end, right before the visitor sees it.
