Did you call session_start() at any point?

Yes. Anyway, the page is calling itself. In order to have set it in the
first place I needed to have called session_start() .

You aren't calling the page, you're redirecting. But regardless, what does that
have to do with session_start() ?

Not necessarily true.

Can you post the complete code for this page, so we're able to see what's going
wrong, because it's not apparent from the snippets you've posted so far.

P.S. You must use an absolute URL in a Location header. But this is unlikely to
be the cause of your problem.

Hmmm, that all looks ok (I haven't actually tried to run it, but I looked over
the code). One thing to check, do you have any whitespace after the closing ?>
in Connections/ssLogin.php? There must be no output (including whitespace)
before session_start() is called...

There is absolutely nothing between that closing and the openning of the
next php for session_start() except that it is on the next line.

Just to be sure, I changed the code to have put them in the same php and had
the session_start() be right after the semi-colon for the require. Same
result.

I meant the closing ?> tag *inside* the Connections/ssLogin.php file.

The closing tag greater-than sign is the very last character in that file.

Ok... the only other thing I can spot is that you need an exit() call after the
header() call.
