Hi there,
Thanks for writing in! I can see lot of JS errors on your site that’s causing by CDN or some plugins – http://prntscr.com/akrs8a
Kindly check your plugins and third party integration.
You could try testing for a plugin conflict. You can do this by deactivating all third party plugins, and seeing if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.
