What do I do when I receive a PHP header error message
Error Message(s):
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /home/content/u/s/e/username/html/file.php:2) in /home/content/u/s/e/username/html/file.php on line 3
Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /home/content/u/s/e/username/html/file.php:2) in /home/content/u/s/e/username/html/file.php on line 3
Warning: Cannot modify header information - headers already sent by (output started at /home/content/u/s/e/username/html/file.php:2) in /home/content/u/s/e/username/html/file.php on line 4
Cause:
This error is caused if the your PHP scripts are printing to the browser prior to sending headers. A common example is printing the html tags prior to starting a session, or setting a cookie. The error tells the line that needs to be altered (in this case, it is on /file.php line 2).
Resolution:
To resolve this error remove the lines from the PHP code that are printing to the browser prior to sending headers.
