I am running W3 Total Cache as a self-hosted CDN. While others have found that disabling CDN or including 'wp-content/uploads/imagerotator.swf' in CDN Rejected Files, allows the slideshow to work, neither is the case for me. The only thing that enables the NextGEN slideshow to work is diabling the W3TC plugin.
Any help or suggestions will be greatly appreciated!
