Hi @phil376, a follow-up on this one. We tracked down the cause: with Jetpack’s Like buttons active, Boost keeps jQuery in its original place, and Divi’s “Defer jQuery and jQuery Migrate” option prints a small script just before it that Boost was moving after jQuery. That script then replaced jQuery, which hid your product images and stopped the tabs from working.
Jetpack Boost 4.8.0 fixes this. If you’d like to give Defer Non-Essential JavaScript another try, update Boost, turn the feature back on, and remove any page exclusions you added for it. You’ll also notice a new dashboard; the Defer Non-Essential JavaScript setting is under Page loading. Let us know how it goes!
