I came across this error when trying to resend a message. What I found is that the plugin expects the body of the email to be stored in a meta data field, but in my case it wasn’t – it was in the post content. So by replacing $meta_values [‘original_message’] [0] with get_post($postid)->post_content in line 134 of Postman\Postman-Email-Log\PostmanEmailLogController.php, I was able to perform the resend successfully.
Disclaimer: I cannot be certain that this is a plugin bug. Perhaps there’s some other reason that the email body wasn’t where the plugin was looking for it.
