I have Drupal 6.10, and am using "private" file-system paths for the file-system configuration.
The Fivestar module works well in every respect except when trying to use custom colored stars. I can create them, and they even appear in the newly created folder in the file system. However, when viewing the pages, it only shows the "default" star type. I tried clearing all caches, changing permissions on the folders it created to allow everyone full access, and neither helped.
