The Page Could Not be reached Error

I read this http://yoast.com/jetpack-and-wordpress-seo/ folowed everything nothing worked. Then, I just deleted jetpack and still not working.

The page at http://www.dexmag.com/2013/02/15/find-out-when-someone-unfriends-you-on-facebook/ could not be reached.

All the problem started after jetpack. Also google plus button donest work.

Any helped would be appreciated. Eveyrh
