[Plugin: WP-Facebook applications] Permalinks not working for custom post types when this plugin is

I am using Sidewinder theme by Graph Paper Press. It has Galleries custom post type and while other posts work, this post type shows 404 page when trying to access via link (other than default permalink). If you have any theme with custom post types, you might want to check. I am not sure if its a theme issue. If you know anything let me know.

Thanks for testing. Can you please let me know which theme you used?

Plugins seems to work fine. It seems this is particular when CPT is used in a theme. I can’t find another theme with CPT but if you find any, please do test it. I used another custom post type code on a different theme and permalinks still show 404 for me.

add_action( 'init', 'register_cpt_gallery' );

function register_cpt_gallery() {

    $labels = array(
        'name' => _x( 'Galleries', 'gallery' ),
        'singular_name' => _x( 'Gallery', 'gallery' ),
        'add_new' => _x( 'Add New Gallery', 'gallery' ),
        'add_new_item' => _x( 'Add New Gallery', 'gallery' ),
