Question

As soon as I load JqueryMobile in my web application I receive this error, unfortunately I’m not able to understand why this problem. Could you point me in the right direction? Thanks!

I fixed this by removing jquery.ui.widget.js which was probably required at some time in the distant past, but not any more.
