Form refuses to submit form data

pcborges · Outubro 9, 2019

Hi, I am struggling to find why my form fails to submit the data on it.

The page code is listed below.

Also the web server (an ESP32 web-server) displays all it receives from the browser.

The alert dialog box shows OK but data on the form is not submitted.

Please check web server printout on page submit

Assistance welcome

Thanks

Paulo

Web Server monitor displays:

Payload is should be the content of the form fields but it comes out empty.

It worked in the past but after several updates it stopped working and I cannot figure out why.

Thanks
