Form "Submit" buttons don't work [RESOLVED]

None of the “Submit” (or equivalent) buttons work on any of the forms on my site no3rdtullarunway.net.au
They worked previously when I tested them but have now stopped!

Hi Mark. That is most likely due to a JavaScript conflict on the site. I recommend opening a support ticket for the issue:

Thanks for your prompt reply Chris.
I was in a bit of a rush so deleted Gravity Forms then reinstalled it and rebuilt my 5 forms and they now work!
Cheers,
Mark
