warning cannot modify header information – headers already sent by (output started at php

This error means that the header is interpreting some space, new line or echo line in wrong way before the call of the function header(“Location: somepage.php”)

Check any echo(“……”); before the header line and comment it while you find the exact line with the problem.

***Español

Este error significa que la cabecera está interpretando algún espacio, nueva línea o un echo de forma errada antes de llamar la  function header(“Location: somepage.php”)

Busque también cualquier echo(“….”); antes de la línea header y coméntelo mientras encuentra exactamente cual es la línea exacta con el problema.
