Hi,
you should receive a reply via email regarding this as well, it would be best if in the reply to the email you could email me link to the page where this problem occurs so i can see how it looks like.
Right now the problem seems to be the customized single.php template file specifically kk_star_ratings() call.
Also, more details are in the email that you should receive via email soon, as this seems to be more installation specific problem rather than general issue with the plugin.
