Hi,

That error means you DID send output before calling session_start().
Try to figure out if you are including anything before that line that
might produce the output, even a SPACE or NEWLINE is output.

I do sometimes use the .htaccess to autostart sessions for a folder: it
is convenient in some situations: nothing wrong with that.
But you better try to find out WHAT is producing output before your
session_start() call.

I would start with:
1) replace the session_start() call with
echo "**TESTING**";
2) Check the output to your browser and see what appears before
**TESTING**, and from there try to figure out what is responsible for
the output before **TESTING**.
