post_excerpt not working

Hi,

Post excerpt does not work.
I remembered this is a tricky one from previous challenges with my own plugin.

Suggestion to solve it:
class-bnfw-engine.php: line 153
$message = str_replace( '[post_excerpt]', ($post->post_excerpt ? $post->post_excerpt : wp_trim_words($post_content) ), $message );

I have tested the above and it works (for me)

Problem is that $post->post_excerpt only works within the loop, and requires setup_postdata and apply filters etc. – did some google ??

Let me know if you choose to implement this change

and an additional wish, can you add a link to the list of shortcode to the page where you add/update the notications (I always struggle to find them)
