On the page that is working, you have this:
HTML Code:
<link rel="shortcut icon" href="http://www.err32.com/images/favicon.ico" />
On the page that doesn't work, you have this:
HTML Code:
<link rel="shortcut icon" href=".ico" />
Have you tried putting the code that works into the non-working page? Also, you may have to clear your cache after changing the code to see if it's working.
