WordPress Bug 902
published
Everyone using plugins with WordPress 1.5 should read bug #902, and apply the patch.
Without this, the admin plugin hooks will break, and only allow you to manage the last-added plugin.
To fix this problem, edit wp-admin/menu-header.php. Find the section that looks like this (starting on line 43):
$page_hook = get_plugin_page_hook($item[2], $parent_file); if ( $page_hook )
Change it to look like this:
$menu_hook = get_plugin_page_hook($item[2], $parent_file); if ( $menu_hook )
