Hi there – sorry to hear you are experiencing difficulties.
It definitely isn’t optimal to load two different versions of jQuery and as it seems to be your theme that is responsible for this I’d strongly recommend taking this question over to them and asking A) how you can dequeue it, and B) if this will indeed have any effect/if foundation.min.js will successfully continue to run with the default version of jQuery bundled with WordPress.
Is that a possibility here? I’m afraid it’s really difficult for us to assess this and really you – quite possibly with the assistance and knowledge of the theme author – will be in the best position to determine if the theme will suffer adversely should those resources be removed.
Is that possible here?
Thanks!
