Like button doesn't work, shows OG error!

I'm trying to use the like button at www.celticridertraining.com/blog/23-cardiff-motorcycle but it gives an error, the exact error is

Your og:type object name has disallowed characters in it. It must match [a-z][a-z0-9._]*

but og type is company and I can't see any other problems, what am I doing wrong please? it's not a problem I have with any other installation.

Typical! it looks like Facebook just took some time to update, it now works!

Sorry to have wasted your time looking
