I'm trying to embed a YouTube video, and received an error:

Notice: unserialize(): Error at offset 452 of 452 bytes in /home/bravohos/public_html/clickandshare.net/modules/boonex/videos/classes/BxVideosTemplate.php on line 64

This is the error that is displayed on the homepage:

Notice: unserialize(): Error at offset 452 of 452 bytes in /home/bravohos/public_html/clickandshare.net/modules/boonex/videos/classes/BxVideosModule.php on line 188
