   I'm having trouble migrating my plugin to 2.7 - an issue with options where it'll show the options page but upon hitting save says "Error! Options page not found."

   I decided to try a very simple example first to isolate the problem, and it's still happening. Could someone take a look at this and tell me what I'm doing wrong options-wise? Would greatly appreciate it...and I'll post later as a generic example for others to use too. The plugin dev docs are kind of fragmented so it's hard to pull together something without looking at about 10 pages...

   <?php
   /*
   Plugin Name: Test
   Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
   Description: A brief description of the Plugin.
   Version: The Plugin's Version Number, e.g.: 1.0
   Author: Name Of The Plugin Author
   Author URI: http://URI_Of_The_Plugin_Author
   */
   
   function my_plugin_activate() {
   	add_option("test", "12345");
   	register_setting('test-options', 'test');
   }
   
   function my_plugin_menu() {
     add_options_page('My Plugin Options', 'My Plugin', 8, __FILE__, 'my_plugin_options');
   }
   
   function my_plugin_options() {
   	register_setting('test-options', 'test');
   ?>
   	<div class="wrap">
   	<h2>Plugin name</h2>
   	<form method="post" action="options.php">
   	<?php wp_nonce_field('update-options'); ?>
   	<table class="form-table">
   	<tr valign="top">
   	<th scope="row">New Option Name</th>
   	<td><input type="text" name="test" value="<?php echo get_option('test'); ?>" /></td></tr>
   	</table>
   	<?php settings_fields('test-options'); ?>
   	<p class="submit">
   	<input type="submit" name="Submit" value="Save changes" />
   	</p>
   	</form>
   	</div>
   <?php
   }
   
   add_action('admin_menu', 'my_plugin_menu');
   register_activation_hook( __FILE__, 'my_plugin_activate' );
   ?>

   Thanks to this blog post I figured it out.

   Here's the modified and working code:

   <?php
   /*
   Plugin Name: Test
   Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
   Description: A brief description of the Plugin.
   Version: The Plugin's Version Number, e.g.: 1.0
   Author: Name Of The Plugin Author
   Author URI: http://URI_Of_The_Plugin_Author
   */
