Problems with javascript since WP upgrade

Hi

I’m using an Able Theme based site (https://fwtest.co.uk) since the upgrade (at least I think this is when the issues started) two things have happened.

1. My Able Theme mobile ‘hamburger’ menu won’t work anymore on either a resized browser or mobile device

2. The Testimonials Rotator (see bottom of above page) has stopped rotating and now just displays a list of quotes.

I’m assuming that both of these use javascript and I’m guessing that they are trying to call something that isn’t there – possibly a version of jquery.

Any ideas?

many thanks

Frank
