The error message indicates that your start_session() call is on line 3
and that output was started at line 2. Try pasting the first 5 lines of
that adminlogin.php script here. The other thing that is normally useful
is to have a look at the raw bytes in the file. Try this:
od -c adminlogin.php | head
from your command line. That will tell you exactly what is in the file.
Sometimes editors try to be a little bit too smart for their own good.
