Question: How Do I change the default favicon?
Answer: To change the favicon you have two options:
First you need to create a favicon.ico file of an image. You can use this handy tool: http://tools.dynamicdrive.com/favicon/
Then you can do 1 of the following...
1. Order the FTP PowerUp (Click "Managed Hosting Panel" at the top of your dashboard. Then click "Upgrades") and upload/replace the existing favicon.ico in the top directory
2. Or Under Media > Add (from your WordPress Dashboard) upload a new favicon.ico. Then under Appearance > Editor open header.php and replace the link to the favicon.ico with the new link to your uploaded images.
Old: <link rel="shortcut icon" href="/favicon.ico" />
New: <link rel="shortcut icon" href="http://mydomain.com/wp-content/uploads/favicon.ico"; />
3. Some themes have a option for uploading a new favicon.ico from within their settings/options page.
