Body element is empty after publishing

I just tried publishing my project and the element is completely empty. There was no problem this morning though. Other projects publish just fine. And duplicating the project did nothing. Any ideas anyone?

Here is my site Read-Only: [LINK]1
(how to share your site Read-Only link)

Got it sorted out thanks to lightning fast support apparently working also on Saturdays :+1:

Here is what they suggested and that did it for me:

When this happens, it is usually due to an unclosed style or other tag when using custom code in the head of the site page, using custom code in site or page custom code section.

Each style tag must be properly opened and closed, if no closing tag to some code in the head, the rest of the body will be rendered in the head.
A good test is to remove all custom code from head and republish.
