Hello!
First of all congratulations for the plugin, is really useful!
When I used it I had some incompatbilities with the qtranslate plugin for instance the title of the post appears three times in the blog, and also in the backend.
I thought it was for the 'post_content', so I changed some lines from related-links.php:
// Check if the post exists
$found_post = get_post( $id );
$language = apply_filters('the_title',$found_post->post_title);
if( !empty( $found_post ) && $found_post->post_status != 'trash' && $found_post->post_status != 'draft' )
{
// Push posts values
if( $post_type == get_post_type($id) || empty( $post_type ) )
{
$values[] = array('id' => $id, 'title' => $language, 'url' => get_permalink($id), 'type' => $found_post->post_type);
}
And I've solved it in the frontend. Hope it will be useful for someone.
bye!
P.D.: If anyone know how to solve in the backend it will be perfect ;)
