Does Anyone Know What Is Wrong With My Wordpress Site

I don’t know PHP, but the site is giving this error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /nfs/c06/h04/mnt/96420/domains/offthepost.info/html/wp-content/plugins/facebook-like-button/inc/rec_widget.php on line 11

That’s not the plugin I deactivated, so it has obviously caused a problem elsewhere.

Any ideas?
