Multi Regen theme not recognizing jQuery

Is where I’m having my issue, everything works but a little bit of jquery, that got loaded last. It was working yesterday but today it’s not. What’s broken is that in mobile view the menu doesn’t drop down like it is supposed to, except on the /services.php page. Which doesn’t make sense to me as they are all the same as far as head tags and Javascript. I posted on stackoverflow to see if it was a code related issue, but it sounds like it is indeed the order being loaded ( http://stackoverflow.com/questions/37212558/jquery-addclass-viewportchecker-is-not-a-function )
But again, why does it do this on two out of three pages? This is my conundrum.
I’m using the multi Regen theme, and I’d contact their support but their contact form isn’t working and I can’t find their email on their site
Thanks in Advance guys!
