You probably have some javascript errors on your page - maybe you're loading jquery twice on the same page for example. Have a look for those first and make sure there's no issues there and your form will work.
It looks like it has javascript error on submit button press:
Error: TypeError: jQuery(...).isStillReady is not a function

try changing site template temporary to one of default joomla templates and/or disabling any 3rd party plugins that might be changing JavaScript on the site on by one to find out which one causes this error.
