what does this mean??
Warning: session_start(): Cannot send session cookie
look in your PHP.ini file and check if your entry looks like this; session.use_cookies=1
are you calling session_start() like this:
<?php session_start(); ?>
From the PHP manual ( http://www.php.net/session_start )
Note: If you are using cookie-based sessions, you must call session_start() before anything is output to the browser.
i checked phpinfo() and my server has session.use_cookies=1
I am also calling session_start()
why do I get this error?
As my quote suggests, you are using session_start() after output. Output is stuff like html. Don't send output before using session_start(), make session_start() the first line.
