Now, I found the problem: Google doesn't show that favicon to some special IPs, like some countries. Also I have that problem with Google main logo. That change never! I could solve this problem by using a VPN account, but now I don't know why Google do this works...
http://www.google.com/s2/favicons?domain=[domain]I don't know why this method doesn't show my blog/many other websites favicons. for example:
http://www.google.com/s2/favicons?domain=baghbagho.com
That doesn't show my favicon, whiles my blog have a favicon.
What's the problem?
