I'm having problems with the plugin tablesorter apparently my system is not identifying the function coo existing, do not know if it may be some conflict with other javascript (I'm making the change in a wordpress plugin).
Below is my code:
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script type="text/javascript" src="jquery.tablesorter.js"></script>
<script type="text/javascript">
(function($) {
$('table').tablesorter();
})(jQuery);
</script>
I changed the way i'm calling the js file
<?php
wp_register_script( 'jquery.tablesorter.js', get_bloginfo('template_url').'/js/jquery.tablesorter.js' );
wp_enqueue_script( 'jquery.tablesorter.js' );
?>
