Due to concerns of possible security exploits, the 1 Pixel Out Audio Player has been removed from PowerPress as of version 4.0.6. PowerPress users are strongly encouraged to update their copy of PowerPress immediately.
If you update your copy of PowerPress via the plugin update interface built into your WordPress wp-admin, no further action is required.
If you update your copy of PowerPress via FTP, it is imperative that you delete the following file in the wp-content/plugins/powerpress folder: audio-player.swf
The possible issue is with the 1 Pixel Out flash based audio player. The official 1 Pixel Out Audio Player was removed temporary from WordPress.org repository (link: http://wordpress.org/extend/plugins/audio-player/) until the security issues have been addressed. Once a new version is available, we will review re-including the player in PowerPress.
If your site is currently configured to use the 1 Pixel Out audio player (pictured below), the Flow Player Classic player will be substituted in its place once your copy of PowerPress is updated.
