I just created and inserted a Favicon on four sites. It went into three of them fine but the fourth site gave me problems. I used the same procedure on all so not sure why it would not show up on the fourth site. I finally got it to work on the fourth site but for some reason, it still does not work on one page within the site. What would cause this?
We'd need to take a look to be sure, but often it takes a browser quite a while to update a favicon. You could try clearing your cache etc. to try to flush out the old info. Otherwise, we need to know what you mean by 'not working'.
