error combination prestashop 1.6

[hydrons 0]

I'm having trouble in the combinations of products, they were made ​​correctly, but the buy button disappears when starting the page, see example 

 

  http://lojapapeldeparede.com/casual/1313-papel-de-parede-com-tons-pasteis-amarelos-roxos-e-bege-casual-01.html#/tamanho-5x0_58_metros 

 

Can someone tell me what is this error and how to solve it?

Unable to solve, all of which have the same upgrade js error which is inside the js folder in the theme the correct filename is product.js.

[El Patron 2,683]

back office-->edit product

 

select quantities

 

do you have quantities defined for product combinations?

I have set 100 for each combination

[El Patron 2,683]

when I look at your page source, I see this: quantityAvailable = 0;

 

I can not explain with info presented why this is so.

Here is a sample of my back office and see what is stated 100 for each combination. 

 

this error happened after version upgrade

Hi, you appear to have a module called productpaymentlogos - try disabling that.

If that doesn't work, try disabling zopim.

Cheers, Dave

No change, the error continues, already updated the errors remain

I believe this error is in the database tables, but even after hours of searching this error persists, the previous update were working properly, it is possible that there was a break in the update file? Or is it just an error code when updating?

[stottycabanas 129]

Is this happening for all products or just this one?

I assume the product is configured as 'Available for order' in the back office product page?

Could you post a screenshot of the Product page part of Preferences->Products?

In addition to the upgrade to 1.6, did you do any individual module updates recently?

Thanks, Dave
