En la respuesta anterior indicaba de que tengo el mismo problema. He realizado varias pruebas y todo está correcto, el problema parece que proviene del servidor donde se aloja la página web, porque he probado otros servidores y funciona perfectamente.
He probado a borrar el archivo que indicas, y se resuelve el problema. Muchas gracias.
In the previous response indicated that I have the same problem. I have carried out several tests and everything is ok, the problem seems to come from the server that hosts the web page, because I have tested other servers and works perfectly. I tried to delete the file that indicas, and resolves the problem. Many thanks. Translation carried out with translator online.
