juansaman on "[Plugin: Youtube Channel Gallery] Forbidden message from YouTube"

Hi,
I'm receiving the error "Message from server: Forbidden. Check in YouTube if the id ****** belongs to a user. To locate the id of your user check the FAQ of the plugin." at a random rate, sometimes the playlists work sometimes don't. Is there anything I could check?
Tested with Wordpress 3.9 and 4.0
Thanks.
