I was trying to get the flickr photo gallery working with wordpress 2.3 and finally found the answer.
It is not tested with WP2.3. For this it doesn’t appear. But I can tell you, that after upgrading to WP 2.3 it wasn’t working. But with a few changes it seems to work with no further problems (I haven’t test it enough).
Just change the following lines in your admin_options_load.php you can find in wp-content/plugins/silaspartners/flickr.
// changed since WP2.3
// require_once(dirname(__FILE__).$tmpPath.’/wp-admin/admin-db.php’);
require_once(dirname(__FILE__).$tmpPath.’/wp-admin/includes/user.php’);
After that it works for me.
