Prestashop 1.6 Error when registering or modifying a product

[Txus]

Error al dar de alta o modificar un producto.
Con la versión de Prestashop 1.4 no tengo ningún problema en dar de alta un producto o modificarlo, pero en la versión 1.6 no se me activan los botones de SAVE.
He probado con Firefox, Explorer y Crome, las últimas versiones.
¿Alguien sabe como solucionarlo? Gracias.

Error when registering or modifying a product.
With the version of Prestashop 1.4 I have no problem in registering a product or modifying it, but in version 1.6 the SAVE buttons are not activated.
I have tested with Firefox, Explorer and Crome, the latest versions.
Does anyone know how to fix it? Thank you.

I'd suggest seeking support with the developer of prestashop, as to me it seem to be an issue with the software rather then the hosting. Perhaps they do require more/other fields to be filled with this version then they did with the older version.

I have personally never used prestashop so I can not give any support for it.
