Doesn't return true excerpt, here's a fix

The slider doesn’t return the true excerpt since the custom post type it creates doesn’t have excerpt support.

Edit testimonial-slider.php and Change line 568

'supports' => array('title','editor','excerpt')

and then to your functions.php add the following:

‘add_filter(‘testimonial_slide_excerpt’,’my_testimonial_excerpt’,10,3);

/* this will return excerpt regardless of the setting in the slider settings */
function my_testimonial_excerpt($excerpt,$post_id,$slider,$css){
$testi_post = $post_id;
if(has_excerpt($testi_post))
{
$testi_post = get_post($post_id);
return $testi_post->post_excerpt;
}
return $excerpt;
}’
