WP Touch Menu problem

I am having an issue with WPTouch – the menu doesn’t work, but only on certain pages. You touch where the menu dropdown should be but nothing happens.

It does not work on the home page or the videos page, but it does work on the contact page, for example. I clicked “Enable jQuery 2.0” setting in advanced settings.

Any other ideas on what could be wrong?

I am testing from an iPhone 5

Thank you!
