Favorite Nodes does not show up under Site Configuration

i have the same problem with it, please help

Same problem here.

You can get to the settings via /admin/settings/favorite_nodes (you can see the paths for the module in the favorite_nodes_menu($may_cache) function in favorite_nodes.module)

but having said that I am having trouble getting any of the functionality working

I also cannot see under administer, but can get to /admin/settings/favorite_nodes, and seems to be working after setup.

here's the solution.
1. open the file favorite_nodes.module, find the function favorite_nodes_menu($may_cache), you're see the code like this:

$items[] = array(
'title' => 'Favorite node settings',
'path' => 'admin/settings/favorite_nodes',
'description' => 'Settings for favourite nodes',
'callback' => 'drupal_get_form',
'callback arguments' => 'favorite_nodes_settings',
'type' => MENU_CALLBACK,
'access' => user_access(FAVORITE_NODES_PERM_ADMINISTER),
);

2. replace the 'type' value MENU_CALLBACK with MENU_NORMAL_ITEM,

3. clear your cache_menu in your db,

4. done. now you should see the menu 'favorite nodes setting' under admin/settings menu.
