variations disappears after editing

[grindto10]

Good morning, everyone,

I discovered Prestashop and started to see how the variations system works.

I created a first product. I added 3 variations, 2 of them with a price increase. After saving and activating the product, it works perfectly well in the shop.

However, when I return to the edition of this product, the variation page no longer shows the 3 variationsI (see image). And therefore it's impossible to modify the product because an error occurs ("Impossible to update the settings").

What's the problem?

Note: I have the same problem when I duplicate the product

The image is in french but you can see 0/3 déclinaisons (so variations) but there none of them below.

Version : 1.7.6.0.

 

Thanks a lot !
