Hi, I have recently moved my RoR app on the Heroku platform, and almost everything works fine apart from the videos. It works fine when my app runs in local but not on heroku. This is the error log I''m getting, if anyone knows where it can be coming from: Processing VideosController#new (for IP at 2010-03-20 04:32:09) [GET] Session ID: 6abecf60c3369d7c7029e366bb801e08
