The error is quite obvious, body is None and thus it doesn't have 'text'
attribute, why body is None is not so obvious since I think selenium
should raise NoSuchElementExceptionif it can't find the body tag, no
tjust returning None. When you manually browse the url, what do you get?
is the body tag there or are your getting a blank page?
