[Problem] Attribute/price issue (0$)

[kmcero]

Hi everybody,

 

I was just finishing my store and suddenly appears this issue when I entry any size attribute in my products as you can see in this picture:

 

 

 

Once I entry different sizes to my product, It generate two problems: 

 

1. Accessing as normal client it shows me product price as "0,00 €".

 

2. Accessing as a preferred customer it does not apply the Group Costumer Discount I choosed for that client.

 

It has just happened once I entry a size (attribute) to that product.

 

This is my store: http://www.kmcero.es/tienda

 

My prestashop version is 1.6.0.9 . 

 

I have just tried lot of methods I could find on forums but any of them can't fix my problem. Some of them become my problem into another one. 

 

Please, could you assist me at this point? Any idea about How I can fix this? I'm too lost and there has been too many months of work...

 

Thank you all!
