Are you performing your redirect after the headers have already been sent? If so it will not work. Please make sure that your code is running before the headers are sent, preferably as part of the template_redirect hook that Wordpress offers.

If you are not sure where your code is being loaded I suggest you incpsulate your code inside a function that runs during the template_redirect hook. For example, you can add the following to your theme's functions.php file:

function handle_session_data()
{
  //Your code here.
}
add_action( 'template_redirect', 'handle_session_data' );

Answer 5

the following code solved my problem

`function register_my_session()

{

if( !session_id() )

{

session_start();

}

}` in function.php

and start the session without any error, for header, i used the java script redirect, this solved my problem
