    Error message when clicking the feedback button

    Asked by Steve on August 29, 2012 at 12:09 PM


    when clicking on the "Send Feedback" button, my Javascript console prints "TypeError: window.getComputedStyle is not a function".

    I'm using Firefox 14.0.1 and Windows 7, but it appears on Google Chrome too.

    Any Idea whats wrong?

    You may directly test it here http://www.jotform.com/wishbox

    My first thought was, that there is a problem with my browser, but after testing on another PC it shows the same.

    The console shows me the source file "chrome://global/content/bindings/resizer.xml"

    I was able to see the error messages as you have mentioned. On my end, however, these errors did not affect how Wishbox works.

    The Wishbox widget in that page worked flawlessly on my tests. Can you please tell us if there's any specific problem you're experiencing with the Wishbox Demo?
