Nothing saving - with text

The backend administrator is not saving anything. Everything I edit will be blank. Everything I create saved will be blank. The item is added in the product page or category but it is all blank.

Any ideas ?

Hi again Michael Huynh,
I have already answered you via ticket system. That because the wrong settings with multiple languages. Please following up the ticket to get it resolved.

Hi Giang,
Thanks. That worked perfectly.

OK no problem at all Michael!

Hi,

I've just bought your componente eShop and installed the Spanish Language Pack. Please give us the procedure to fix this, we need to deliver this as soon as possible.

Using the Admin Backend, when creating products, nothing is saved although it says that The product was saved correctly.

As you can see, we need this component in full spanish so that we need the translation pack.

Thanks for your help.

Hello Erick,
The problem caused by wrong setting in the multiple languages plugin. If you site only use Spanish, please go to Extensions->Language Manger, then find and unpublished 2 following language plugins: "System - Language Filter" and "System - Language Code"
After unpublished these 2 plugins, try to create products again in EShop, it should work.
Please try and let me know the result.
Sincerely, Giang
