Fix youtube preview parsing in Production.

You can see from the thread that Vimeo links are working via oEmbed in production, but for some reason the youtube parsing is not working. It works perfectly fine on my local environment, so we need someone to work with Nuno or MrPunyapal who have access to logs etc, to try and work out why it's not being parsed correctly in the production environment.
