Enabled SSL https dns cloudflare

I'm having issues with Upfront not loading correctly after enabling https on wordpress.
I have a cert from letsencrypt and cloudflare setup to strict SSL.

I believe it the issue lies with jquery not being called using https but not completely sure about what is causing the issue. I've been poking around changing http to https but don't want to make to many edits blindly.
Do you know what php or conf file I should be editing?

Thanks for your help,
