    No output of anything before complete processing. For this you can use ob_start (), ob_end_flush (), ob_flush () (For documentation in search engines). The rest is the usual redirect using header. And by the way, the header is already sending data. - Adokenai

The error indicates that the headers have already been sent. See if there is any output ( echo , print , etc.) before session_start() ;

And read the mistakes! What do you have in the do_login.php file on lines 14 and 24?

  • There is nothing like that before session_start (); no, neither in nor in the handler ..14 p. session_start (); 24 p. Echo ("No contact!"); Actually, I cited the do_login.php code as an example; this is all code - Game Bro
