"dns_probe_finished_no_internet" on a MAC

This has only been happening for about a week. Every time I try to go on any website on my Mac I get this error "DNS_PROBE_FINISHED_NO_INTERNET" I have been searching for answers and the only ones I can find are for Windows users. Again I have a Mac OS X 10.7.5 . If you can help it would be very appreciated.
Thank you all. Bless you.
