I validated my website using: https://validator.w3.org/#validate_by_uploadand I got no errors. However, the website recently changed and now I get these 2 messages:
Info: The Content-Type was application/octet-stream. Using the XML parser (not resolving external entities).Fatal Error: Empty document, with no root element.
What do these messages mean? How do I correct the error?
The settings I used were: Encoding: utf-8 document type: HTML5
SIMPLE HTML:
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Title</title><link href="css/omnicode.css" rel="stylesheet" type="text/css"><!--[if lt IE 9]><script src="http://html5shiv.googlecode.com/svn/trunk/html5.js"></script><![endif]--></head><body><div class="container"><header><h1>Header</h1></header><hr><p> TEXT </p><hr><footer>Footer</footer></div> </body></html>
