Hola amigos me he descargado un script para montar una web donde los usuarios pueden registrarse para hablar de lo que quieran, la cuestión es que el formulario de registro no funciona y arroja el error "Could not open socket" he probado cambiando las claves del api del captcha pero no entiendo demasiado bien ésto de php.
Hos pego los códigos implicados:
