usually that line ends in a file name and a line number....

[Kingy]

yes.. index.php and line 3.. exactly where session_start is

You must have output (usually white space) outside of the <?php ?> tags.

ob_start(); sends header information thats why.

 

and what use is this for?

ob_start(); sends header information thats why.

 

and what use is this for?

 

ob_start() does not send any headers. It creates a buffer for output to go into, untill that buffer is sent no headers (or output) will be sent either.

 

Output buffering is often used as a hack around header errors.

The error message contains information about where the output occurred in addition to what code could not output headers. By just posting bits and pieces of the error, just means that it will take a really long time to give you a direct answer that solves your problem.

 

If you are not going to read what the error message states and try to figure out the problem yourself, then you must post the entire error message if you want someone else to help you. xxxxx out any sensitive information such as account/domain name in the file paths if you don't want that information posted.
