block UI jquery error

I have just updated to WP 3.9.1 and Jigoshop 1.9.6 and I am getting the following jquery error when I access any of the jigoshop backend settings pages. I have disabled ALL plugins with the exception of jigoshop and I still get the error. I only get the error when accessing jigoshop settings pages. Front end pages do not give this error and function correctly.

The error is “blockUI requires jQuery v1.3 or later! You are using v1.11.0”

Can anyone advise the quickest fix as this is the only error I am seeing on my test site.

Many thanks
Tim
