Problem with butto IVR

Hello, I’ve install asterisknow with freepbx. I had to update my asterisk and now when I enter to the module IVR, the button “Add a new IVR” appear, but when I click it nothing happens. I need to configure and IVR, this is a simple: he caller should hear the welcome message, and then dial the extension number.
Please help me, how I can fix this bug of the IVR or wich is the another way to realize that “IVR”.

Best Regards.
