I also have this problem. Starting From 12pm. First it was Internal server error, now it is cannot display webpage.
And this time was different than the last problem. The last problem was the out-dated joomla for me but this problem, I even tried to upload random files but it only said cannot display webpage. Is this a server side error or a user error? Oh, and it only displays the web sometimes then goes back to these errors.
