Failed to execute 'appendChild' on 'Node': This node type does not support this method

hi I tried to add a netlify form in my blog but it seems not working
<form name="contact" method="POST" action="/" data-netlify="true"> ...... </ form>
when I fill some data to the input, I got no submitted values but I have this error
Failed to execute 'appendChild' on 'Node': This node type does not support this method.
can any advice?

Hi, @ijelliti, and welcome to the Netlify community site.

This Support Guide is the first port of call to debug any forms issues. There are also many other Support Guides for forms - you can find them here: #Netlify-support:support-guides

We also recommend trying to search the forums or look at topics tagged Netlify forms if you haven’t already - it’s likely your question was already asked by someone else!

If you are still having problems, please provide more information such as what you have already tried, and a link to your live form. :slight_smile:
