leviticus,
Thanks for getting in touch and sorry to hear you’re having trouble here, but hopefully I can help. I’m seeing a javascript error when viewing your site in responsive mode (screenshot). Can you try temporarily disabling any template overrides you’ve performed to see if this resolves the issue? It’s possible that you have some out-of-date template files that might be causing this, or you’ve made a modification that is conflicting with what the JavaScript is expecting.
Give that a try and let me know what you discover. Thanks! ๐
