I have a site using a custom favicon.ico. The favicon displays as expected in all browsers except IE. When trying to display the favicon in IE, I get the big red x; when displaying the favicon in another browser, it displays just fine. The page source includes and it does work in other browsers. Thanks for your thoughts.
EDIT: SOLVED: The source of the issue was the file was a jpg renamed to ico. I created the file as an ico and it is working as expected. Thanks for your input.
Right you've not been that helpful (providing source would be have been really useful!) but here you go... Some things to check:
Is the code like this:
<link rel="icon" href="http://www.example.com/favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="http://www.example.com/favicon.ico" type="image/x-icon" />
Is it in the <head>?
Is the image a real ico file? (renaming a bitmap is not a real .ico! Mildly different format)
Does it work when you add the page as a bookmark?
