My web developer thinks that Rocket Loader is preventing the zoom facility working on our products page, is there a workaround for this/
You can disable Rocket Loader in the Speed settings for your domain.
You can also disable it through a Page Rule.
It worked! Are there any disadvantages to disabling it?
Are there any other things we should consider implementing?
No real disadvantages. If you’re running HTTP/2, automatically provided by Cloudflare with HTTPS enabled, it’s pretty quick.
Rocket Loader is pretty slick and can help some sites, but I generally leave it disabled for less hassle/worry.
