I got an issue with my favicon too
I created a .ico favicon and uploaded it to "/public_html/mywebsitename.com/wp
-content/themes/classipress1/images" replacing the favicon that was already there
The favicon didnt appear so after searching the forums I added this code to header.php between the <head> and </head> tags:
<link rel="shortcut icon" href="<?php bloginfo('template_directory'); ?>/favicon.ico" />
I also cleared cookies and cache and refreshed loads of times but the favicon that shows up is still the classipress one.
