AutoComplete Post Search not working

Thanks for using our plugin.
Make sure you have not checked your post type in check box by going through Auto Post Search menu.
You are using shortcode in file template or in widget?

If you are using shortcode in widget, you will have to make widget supported for shortcode by putting following code in function.php file.

add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');

Let us hear from you soon.
