 * Hi,
 * I am using WordPress as a kind of CMS for my website, I use the comment function
   not as a comment-system but I use it as a guestbook.
    For this purpose I want
   to change the mail that is being send when someone leaves a comment, so in my
   case a new entry to the guestbook. I want to change the text and I want it to
   be send to another mail-address then the mail address of the admin.
 * After a little search I found out that this mail-function is implemented in the
   file pluggable.php in the function wp_notify_postauthor. I found out that you
   can override pluggable functions with a plugin, so I thaught it would be the 
   best solution to write my own simple plugin for this.
 * I never wrote a plugin before, but with some help from several websites I thaught
   I managed. I wrote the next plugin to override the wp_notify_postauthor function:
 *     ```
       <?php
       /*
       Plugin Name: Guestbook Notifier
       Description: this plugin changes the mail that is being sent when someone writes something in the guestbook
       Version: 0.5
       Author: MaartenN
       */
       ?>
   
       <?php
   
       if ( !function_exists('wp_notify_postauthor') ) :
       function wp_notify_postauthor($comment_id, $comment_type='') {
   
       	$guestbooksender	=	'blah@blah.com';	//the address that will be seen as the sender of the mail
       	$guestbookreceiver 	= 	'blah@blah.com';	//the address where the mail will be send to
   
       	$comment = get_comment($comment_id);
   
       	$from = "From: \"".get_option('blogname')." Guestbook\" <$guestbooksender>";
       	$reply_to = "Reply-To: $comment->comment_author_email";
       	$subject 		 = sprintf( __('New message in your guestbook'));
       	$message_headers = "MIME-Version: 1.0\n". "$from\n"."Content-Type: text/plain; charset=\"" .get_option('blog_charset')."\"\n";
       	$notify_message  = sprintf( __('New message in your guestbook')) . "\r\n";
       	$notify_message .= sprintf( __('Author : %1$s'), $comment->comment_author) . "\r\n";
       	//and here are some more lines added, but to keep it readable in this forum, I deleted them.
       	//the lines I deleted are the same as the above line; they add a line to the text that is being mailed
   
       	$notify_message = apply_filters('comment_notification_text', $notify_message, $comment_id);
       	$subject = apply_filters('comment_notification_subject', $subject, $comment_id);
       	$message_headers = apply_filters('comment_notification_headers', $message_headers, $comment_id);
   
       	@wp_mail($guestbookreceiver, $subject, $notify_message, $message_headers);
   
       	return true;
       }
       endif;
       ?>
       ```
   
 * But when I activate this plugin, it does what I expected it to do; the mail-text
   is changed and it is being send to the specified mail-address in the plugin, **
   but I’m not able to publish new posts anymore**. When I write a new post, and
   I press the publish-button, WordPress tells me that my attempt to edit the post
   failed.
 * Do you know a solution for my problem?
    Or do you know another solution to change
   the text and the recipient of these mails?
 * Thank you very much!
 * MaartenN

 * I have almost the same problem:
    I wrote a plugin to change the looks of the 
   login-screen, this works, but I am also not able to publish new posts, I get 
   the same error-message as MaartenN and the posts are stored as not published.
 * does anyone know how this is possible, and more important, how we can solve this?
