Hola,
sigue dando error, yo creo que el Header esta mal, por que uso Netbeans, el editor de php y se pone en amarillo cuando pongo este trozo de codigo.
¿...?
Código:
Warning: Cannot modify header information - headers already sent by (output started at /home/formularios/sample-html-simple.php:12) in /home/formularios/contact-form/contact-form.php on line 197
Warning: Cannot modify header information - headers already sent by (output started at /home/formularios/sample-html-simple.php:12) in /home/formularios/contact-form/contact-form.php on line 201
Muchas gracias
