Error Message on Form Submission -#2

I created a form submission page in Dec 2015 and Tested it to make sure it worked, and it did.  Now in January 2016, when a customer and myself tired to use again, I received an error message that Method Not Allowed.  The requested method POST is not allowed for the URL /index.html.  Apache/1/3/41 Server at aquaticrealmscuba.com Port 80

While the request was still sent to our e-mail, it appeared to the customer that the request did not work.

Can you assist with what needs to be done to eliminate this error messages for our customers?

While reviewing your form, I was able to replicate the issue. Could you please indicate if you are trying to pass values into your page?

I did notice that you have the option SEND POST DATA enabled.

If you remove this option in the Preference option, you should no longer get the error.

I made the change and the Submission form works again.  Thank-you

On behalf of my colleague, you're welcome.

Do let us know if you need more help, we will be glad to assist you.

Regards.
