Hi @elliot,
It turns out that its another plugin that is putting jquery migrate in there. This is turning out to be a bit more complicated than I anticipated.
I think I am just going to focus my energy on cacheing.
To answer your question the add-ons are fairly recent. I think I bought them in October. Probably not old enough to warrant jquery migrate. I have included them in the theme so I’m a bit hesitant to update them even though I noticed there is an update available.
Thanks so much for your help.
