Puede ser que firefox deshabilite los referers?
Cita: I got this error too, it was caused by "referrers" being disabled in Firefox... The issue was resolved by using Internet Explorer for the task...
Tengo un formulario que usa esto:
Código PHP:
<input name="referer" type="hidden" value="<?php echo $_SERVER['HTTP_REFERER']; ?>" />
Y cuando quiero recibir ese formulario con php, firefox me tira error!
Cita: Notice: Undefined index: HTTP_REFERER in C:\wamp\www\manual26\AoI Manual\Library\login\loginForm.php on line 83
Warning: Header may not contain more than a single header, new line detected. in C:\wamp\www\manual26\AoI Manual\Library\login\login_script.php on line 70
Ademas hay un segundo error respecto a headers... ¿?
