On this site, on my iphone only (but not responsive view or emulators) my mobile hamburger menu is broken if ACF plugin is activated
https://beechers.darkstarmedia.net/
I have tested this extensively, the problem is 100% the ACF plugin. Is there some sort of jquery conflict with the plugin?
it works on my apple PC safari, chrome, firefox, regular and responsive mode. iPhone Simulator, Andriod studio.. just not an iphone
You are running 2 versions of jQuery.
Try removing your manually added 3.3.1 or set WordPress not to load the 3.6.0 min.js .
Looks like rocket-loader isn't seeing jQuery. I'm assuming its the Cloudflare plugin? if so, could try disabling it. –
