Not woking with WordPress 3.5

Since upgrading to wordpress 3.5 I can not get this plugin to work, I am getting errors like:

“Views Today: Warning: Missing argument 2 for wpdb::prepare(), called in /var/www/vhosts/xxxxxx.com/xxxxxx/wp-content/plugins/post-views/post-views.php on line 2517 and defined in /var/www/vhosts/xxxxxx.com/xxxxxxx/wp-includes/wp-db.php on line 990 80″

I have replaced the url with xxxxxx for security purposes. If I disable the plugin, the errors go away, but I was using it on a lot of pages on the site…. Any help would be appreciated.
