Error retrieving, channel information Developer backend

On my Roku device, my channel comes up, and the videos plays just fine. How ever in the back and when I tried to click on preview channel I get an error. ( there was an error retrieving your channel information. Please try again by refreshing browser or contact customer service) this started since yesterday when I added more videos. Can anyone help?
