Hola, tengo el siguiente problema, no logro programar un gestor que me permita subir archivos grandes (más de 1MB) a un servidor a través de una interfaz web. Me bajé un código (free) de la red y lo implementé y me da errores que asumo son por cause de un timeout del servidor durante la subida de los archivos. Hablé con mi proveedor de hosting y me dicen que subieron el timeout, sin embargo sigue sin funcionar.
Les copio el código y el error que me devuelve. Saludos y espero por su ayuda:
