@igmoweb I just sent you an email saying that this should do it. However, I just realized that the plugins_loaded action is too early to properly detect whether or not to override Hummingbird's handling of the Divi Builder scripts. Really the action hooked on line 62 (with priority 1) is the earliest. Can you make this work on your end using that hook and priority instead of plugins-loaded?

_Edit:_ Ah, nevermind. Init would obviously be too late. I just noticed something else, I'll email you the details.
