Posting YouTube links on Facebook - No thumbnail?

[sj33]

I've been having a rather annoying problem recently where any YouTube video I post on Facebook does not display a thumbnail or info like it used to, just the title and link. I assumed it was the vids that I was trying to post, but it happens with everything. Looking around on Google, it seems to be a common problem. Some have suggested adding a ';' to the end of the link, but this does not work for me.

Any ideas?

Facebook was doing this for me about a month ago but has been fine recently, although I haven't posted a YouTube video for a few days.
