It actually looks like a favicon isn’t included in that template. You can still put your own in by placing the favicon into the template files and inserting the code into the head of your index file.
Basically just create yourself a custom favicon.ico file and place it into either the templates main file directory or sometimes I like to keep mine in the site’s main images folder.
Then insert the following code into the head of the templates index.php
<link href="/templates/ja_mageia/favicon.ico" rel="shortcut icon" type="image/x-icon" />
or
<link href="/images/favicon.ico" rel="shortcut icon" type="image/x-icon" />
depending on where you place the favicon. I hope that gives you a better idea.
