Need help! Please.

Hi there.

Recently I got Soft Rejection for my new template. Only one issue >> Code Validation.

I have all 6 pages. And I validate all pages in https://validator.w3.org and 5 pages are perfect.

Only in Contact Page I got this error:

IO Error : HTTP resource not retrievable. The HTTP status from the remote server was: 409.

What is this? How can fix it?

Really appreciate your help.

Best Regards.
