Thanks :)

I'm upgrading a plugin to use the administration menus, rather than editing within the plugin itself. I have used admin functions before (such as add_action), but for the life of me I can't figure out why I'm having problems adding it this time around.

Basically, on activation of the following plugin I get a "this plugin has caused a fatal error" (but it is activated), and on deactivation I get "Warning: Cannot modify header information - headers already sent by (output started at /home/britain/public_html/forum/bb-plugins/top-posters-code.php:32) in /home/britain/public_html/forum/bb-includes/pluggable.php on line 232".

Here is the code

<?php
/*
Plugin Name: Show Top Posters (backup)
Plugin URI: http://www.gospelrhys.co.uk/bbpress-plugin-show-top-posters
Description:  Readers with the most postes are displayed on your bbpress forum, with their names (linked to their website if they provided one).

add_action('bb_admin-header.php', 'show_top_posters_admin_page_default');
add_action('bb_admin_menu_generator', 'show_top_posters_add_admin_page');

function show_top_posters_add_admin_page() {
	bb_admin_add_submenu(__('Show Top Posters'), 'use_keys', 'show_top_posters_admin_page');
}

function show_top_posters_admin_page_default() {
	echo "test";
}

function show_top_posters_admin_page() {
	echo "test";
} 

function show_top_poster_text() {
	echo "test";
}

?>

Any suggestions?
