If you are running osCommerce on the web server where PHP’s session.auto_start is enabled, you will receive the following error message:
Warning: session.auto_start is enabled – please disable this php feature in php.ini and restart the web server.
To get rid of a warning, follow these simple instructions:
Open:
catalog/includes/application_top.php
Find:
define('WARN_SESSION_AUTO_START','true');
and replace with:
define('WARN_SESSION_AUTO_START','false');
Save and close this file and it’s done!
