Favicon Troubleshooting
Nine times out of ten it's caching, a path, or a content type. Here's how to tell which.
A favicon that doesn't appear is frustrating precisely because there's no error message — the browser just quietly shows a blank page icon. The cause is almost always one of a handful of things: an aggressively cached old icon, a relative path that resolves differently on a subpage, a file served with the wrong MIME type, a tag that iOS ignores, or a CDN returning HTML where an image should be. These guides work through each symptom to its actual cause, with a way to confirm the diagnosis before you change anything. If you'd rather skip straight to a verdict, the Checker inspects a live URL and reports what it finds.
