Feed Has disappeared…

Hello – hope you can help – A feed on one of my websites has just stopes working and I can’t see why?

I believe I have turned off any add blockers and I have Checked the page settings to see if I’m blocking anything and It doesn’t seem o be the case…

My site is here with the feed at the bottom: http://www.synergypersonnelservices.co.uk and the Facebook page is here: https://www.facebook.com/Synergypersonnelservices

It seems to work with other pages, which leads me to believe its something to do with the url or page itself… any hep would be massively appreciated 🙂
