I have an old PHP page without sessions. When the user submits the

If I now have that PHP page require another page that uses
session_start, when the user submits the form, and then clicks the
browser back button, the prior form data is lost.
That has to be your code re-setting the session variables or something.
PHP won't do this automatically for you.
I even modified my code to check for isset($_SESSION) to not call
session_start again, but no joy.
$_SESSION doesn't exist until AFTER you call session_start ;)
