i can not chage favicon

Hi,
I can not change favicon
"Opera users may need to completely clear their cache in Tools/Preferences. Chrome: Shift-F5. If this doesn't work you will need to delete the temporary internet files and the history and then open your page again. Or delete your favicon, refresh the browser with F5, then upload the favicon."
Done it all and still not updating...
Can You help, please?

Hi there,
please wait 2 days. Sometimes the favicon is cached by servers... or any other cache tools from PHP.

Actually, I took 12 hours in my case.
Everything OK now
Thanks
