To change a favicon and make sure that the new favicon will be displayed instead of the old one, an easy and dummy way is to change the name of the favicon, you don't have to call it favicon.ico, call it anything.ico and put the usual line of code in the head section:

<link rel="shortcut icon" href="interdit.ico"> 

and upload the ico file : anything.ico (change anything for whatever you want).
