I managed to get rid of the 404’s thrown when WordPress installation url is different from the blog’s home page by editing the line 488 of yak-utils.php
function yak_get_blogurl() //This originally sets
$url = get_bloginfo('wpurl'); // the installation directory
// changing it to:
$url = get_bloginfo('url'); // the Word press blog’s home page
In the original form the installation url and home page of the wordpress site had to be the same for the plug-in function correctly. After editing, these URL’s can be different and the plug-in hasn’t broken.
Still observing though.
