   This is the code from WORD PRESS CODEX

   <?php
   add_action('admin_menu', 'my_plugin_menu');

   function my_plugin_menu() {
   add_options_page('My Plugin Options', 'My Plugin', 8, 'your-unique-identifier', 'my_plugin_options');
   }

   function my_plugin_options() {
   echo '<div class="wrap">';
   echo '<p>Here is where the form would go if I actually had options.</p>';
   echo '</div>';
   }
   ?>

   I copy it, and literally and it does not work.

   When I made adjustments it does not work.

   I get these messages

   Warning: Cannot modify header information - headers already sent by (output started at /home/kieran/public_html/sampletucson/wp-content/plugins/permalinkboxcontroller.php:12) in /home/kieran/public_html/sampletucson/wp-login.php on line 287

   I tried using __FILE__ as the identifier and that did not work either.

   HELP!

   I think 2.8 is not compatible with old menu codes.

   Try this, i know this works because i've just pulled it from a basic plugin i have running on 2.8...
   

   <?php
   add_action('admin_menu', '_add_options');
   
   function _add_options() {
   	if (function_exists('current_user_can')) {
   		if (!current_user_can('manage_options')) return;
   	}
   	else {
   		global $user_level;
   		get_currentuserinfo();
   		if ($user_level < 8) return;
   	}
   	if (function_exists('add_options_page')) {
   		add_options_page('Title for the page', 'TheMenuTitle', 8, __FILE__, 'yourfunction');
   	}
   }
   
   function yourfunction() {
   
   	echo 'Hello World';
   }
   
   ?>

   Hope that helps...
