I'm getting favicon.ico error

I have had this error for some time as well. It might be some kind of netbeans bug that has to do with netbeans connector. I can't find any mention of favicon.ico in my code or in the project settings.

I was able to fix it by putting the following line in the head section of my html file

<link rel="shortcut icon" href="#">

I am currently using this in my testing environment, but I would remove it for any production environment.

The accepted answer didn't work for me, I had to add a value to the href attribute:

<link rel="shortcut icon" href="#" />

The accepted answer didn't work for me so I've found this solution.

It may be related to the HTML version as the most voted solution there states:

If you need your document to validate against HTML5 use this instead:

<link rel="icon" href="data:;base64,iVBORw0KGgo=">
