I think what he is talking about is the same problem I'm having, which is still on his web site.
I installed some of your products and your logo "Joomla Theme JEZ Rego Live Demo" has taken over the tab next to the Favicon.ico image and I can't get rid of it, just like the person who started the topic.
After an exhaustive search to remove it manually,I've uninstalled everything JEZ one at a time and it's still there. Please help.
