Upgrade Prestashop Products without avaibility

[jacopocappelli]

After upgrade to Prestashop 1.7.6.1 all products become unavaiable, without stocks.

I try many methods:

• 1 click upgrade
• manual upgrade
• step upgrade (with multiple upgrade from intermediate version)
• new installation with database restore + database upgrading

All methods have same results, all products are not avaible for sell online.

What I can do?

Thanks,
Jacopo
