Question

I have some code which works fine on one server but is giving a session header warning:

Warning: session_start() [function.session-start]: Cannot send session cache limiter – headers already sent

on another.

I have checked the php.ini settings on the two servers and they are identical.

I know that the warning message is supposed to suggest that something has been outputted before the session_start but what I don’t understand is why the same code works on one server but not the other.

Is there anything else that could be explaining it other than the php.ini settings?

I have checked the php.ini settings on
the two servers and they are
identical.

I think you’re wrong, and one of them has buffering on.
