Linkedin not picking up meta-data

My site is: http://Cloudbestpractices.net

I have installed and activated the plugin but it isn’t working. Linkedin won’t pick up any meta data, show any text, images etc.

I think it may be another problem, my site worked fine for ages, without any additional social graph plugins, and then the web host seemed to have some technical problems, and then after that it stopped working.

I have tried installing modules to get around this, and can get it working now for Facebook, but still no success with Linkedin, despite having installed this specific plug in.

Any ideas?

Thanks Neil.
