Fix php issue with website built with Kohana framework

Hi. I am looking for a Kohana php specialist to solve a small bug in my site. The bug is related either to a php error or to facebook api issue. I estimate it shouldn't take more then 30 minutes to solve. You can see the bug upon visiting the site on: [login to view URL] Bug description: [login to view URL] site allows the user to submit youtube video to the website. upon registrating an acount the user can paste a youtube link and begin the process of adding it to the site. This has worked untill a few monthes ago when suddenly some error or API change in youtube prevented this function to go well. I need someone who will check what error prevent the submition of the youtube link to the site and fix it so the process can commence again and youtube links can be submited with the system. This bug was fixed a few monthes ago and now it reapered again.
