Imam mali problem s jednim PHP kodom koji je radio na starijoj verziji MySqla ali na novoj ne radi pa pomozite. Error koji dobivam je "Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\checklogin.php:6) in C:\xampp\htdocs\checklogin.php on line 38". A linija 38 glasi "header("location:admin.php");". BTW. Ovi podatci su moj doma server testni tak da se ne uzbuđujte.
