I faced this problem as well. Then I thought ..... hummm, I will go look at my site from a different PC. Lo and behold, I could see my favicon.ico that I had replaced Joomla's with.
So I went to your websites, and good-news, I see your favicon.ico on both sites.
It seems that those ole Joomla favicon.ico's stay for the long haul in the cookies and are hidden somewhere. Nonetheless, it does work to simply replace yours with theirs!
It's from what PC after doing so that matters.
I love Joomla, but when things go weird like the Twilight Zone, they get real weird!
Happy Jooming!
