We are evaluating Kaltura to host all of our videos and audio for our church. Eventually we'd like to stream this content to mobile and other devices (roku, etc). For now, however, we are just trying to integrate it into a WordPress site that we are building (maybe as a replacement to what we currently have). I'm running into a problem with the installation. The install is successful and I'm able to enter my partner id and log in, but when I try to add a new post the "Add Interactive Video" is blank (the "Browse Interactive Videos" contains the sample videos as well as a couple that I uploaded as a test). I also find that when I log into Kaltura.com and click on Settings -> Integration Settings the "Notification URL" shows http://gator1711.hostgator.com/~sgchurch/church/kaltura/notification_han... . This is our temporary domain until we decide about promoting it to production. When I click on "Ping URL" it fails and I can't find the notification_handler file that it is looking for on my site. I've searched through the forums and other sites online and can't find a solution so I'm hopeful that you can help me.
