hey dorin,
sounds like something went wrong with your update to the latest easysocial version. this post, with the same error, might help you out: http://stackideas.com/forums/streams-in-1-2-17-default-behaviour

if this doesn't fix your problem please provide us with your backend access and ftp details so that we can investigate this directly at your end.
