I checked your form and I can see that you're using Wordpress. Please try to re-embed the form using the iFrame method.
I cloned your form and did a test submission, it went out fine. I was able to submit the form successfully and saw the thank you page after. However, it is a stand alone form and it is not embedded on a web page or in Wordpress page.
Hope this works. Let us know if you need any help.
