Thanks for your feedback. We have isolated the issue to the Multiple Event Registration plugin, an important add-on for Event Espresso that allows users to register for more than one event/class/workshop at a time. With that in mind, we need to keep that plugin enabled.
We’ve made numerous modifications to the theme, so I imagine that’s the issue, yet we can’t find a fix. Perhaps we don’t need the “pointer above menu” function at all. What exactly does that do? As a test, I commented out that entire function and the “undefined” error indeed goes away. Could you tell me the risks of NOT having that function running within the theme?
Great themes and support at Kriesi.
