Connected to FB get yellow triangle with exclamation point in the middle and it says error on page. This happens when the application is just about loaded. It does not complete the opening of the application.
Which web-browser, and where on the screen is the yellow triangle? If it's IE (probably is if it shows yellow triangle) try refreshing page (F5). Facebook.com has loaded okay for me just now with both IE9 & FF12 (though not signed-in, don't use it).
