Jennifer, one thing worth doing is to check the Javascript console for errors in a separate tab (I would suggest actually clearing out any existing errors from the console immediately prior to attempting to load the patron interface). You can find the Javascript console under Admin -> For Developers -> Javascript Console. You may need the DEBUG_CLIENT permission to select it. Errors here could give us a clue as to what is going wrong.
