Hi, I've been building a site with PHP 5 on my develop machine. I've been woring alot with session handling. For example I've been using session_start() now and then depending on where the user/vistor are or are doing. But now I've moved the site to a host server with PHP 4.3.8 and now I keep getting error messages all the time where I use session_start(). The error message looks like this: Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /var/www/html/index.php:9) in /var/www/html/index.php on line 82 But I found out that if I put the tag in the absolute top of every page it seems to work. But then I need to do alot of changes on all the pages. Does anyone know if there's any workaround for this? Thanks in advance // Jonas -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php I bet the reason you're seeing this now is because your local machine

is configured to have X amount of output buffering while the server is not. If you make two scripts that have... <?php phpinfo(); ?> ...on the remote and local environments you can check this by looking for "output_buffering." On some it is set to 4096 by default, while others are not. Do what Nicolas Figaro said and also check for any whitespace or line returns outside of your <?php ?> tags.
