youtube channel fatal error

I had 5 videos in my youtube playlist and everything worked great. I added a 6th video to my play list and went back to my web page and received the following error when I tried to view my video page

Fatal error: Cannot use object of type WP_Error as array in /srv/disk10/1901165/www/iwbocce.co.nf/wp-content/plugins/youtube-embed-plus/youtube.php on line 953
