Browser won't refresh or update


New here and new to hope I am doing this correctly. I bought a Samsung Captivate last week and was loving it until today. When I pull up CNN in the browser (both by bookmark, and by typing in manually), CNN pulls up yesterdays news rather than todays. Also, when I try and log in to facebook it does nothing. I don't even get a green bar at the top like it trying to pull up or refresh or anything. I did some research online and the only suggestion I found was to go to setting and clear the cache. I have done that, but it did not help. The phone is useless if I can't pull up current websites.:thinking: Any ideas would be appreciated.
