Looks like someone's tweaked the error reporting level so it's on E_ALL,
which can be a somewhat alarmist setting :-)

Are you on a shared host, or is there someone else who admins your box? If
so, have a word with them and see if they've been fiddling with php.ini -
that's where the error reporting level is set.
