The instance used to have the automad favicon.ico showing up, but after I overwrite with my own .ico file, it stops generating the html code in the DOM. Can you think of anything that might cause this?
inxeption_dev I solved the issue by add this to the header.php instead of trying to call the favicon snippet.
<link href="/shared/favicon-16x16.png" rel="shortcut icon" type="image/x-icon">
There is a variable called favicon for that purpose. The markup will be generated when that variable is set to an actually existing file.
