Just look here

Hi all!
See i am having problem here and dont know from where it comes from, i am totally a beginner here!.
The Theme Garland runs perfectly but when i tried to upload my favicon. there is no blank page in favicon and not mine favicon..
When i changed the logo, the logo is gone and instead of it text is showed up.
When i tried to change the colour scheme, the scheme remained same i.e. blue.
So i downloaded a new theme which is aqua marine...
So i have uploaded these 2 pics
1. local view on xampp
2. hosted view
