Hi there,

I'm also facing same issue. It has any affecting area.

Currently everything working fine.

What could be the ultimate solution for this.

Hi Mehmet,

What browser are you using? Are you experiencing this behavior on IE 11?

If you are using Google chrome what is the version number?

Thanks.

Have you written an XML request in the Javascript library registered in the form? It can lead to this error.

Hope this helps.
