I upgraded my blog to WordPress 2.3 when it released last week and had a great deal of trouble trying to get things to work out here.
This is one major release of WordPress, that really requires you to check all your plugins.
The current version of the plugin throws up a
Fatal error: Cannot redeclare get_users_drafts()
This has happened because WordPress 2.3 has done away with admin-db.php and now uses user.php to call the same function.
I found a solution in the Flickr Forum. Open
wp-content/plugins/silaspartners/flickr/admin_options_load.php and find
// changed since WP2.3 require_once(dirname(__FILE__).$tmpPath.'/wp-admin/includes/user.php');
This should fix the error and get your album working perfectly once again. Just need to wait till the author fixes this.
