I can confirm that after disabling Product Filter by WBW product variations are working again.

Thank You @leopap

I use Generatepress theme and I switched to Storefront but problem is the same. In front end there is variations but in back end there is no variations but attributes are there. If I try to generate variations form attributes do you think I can resolve the problem?

P.S.

In every product on VARIATION tab I see only one variation with same number #2175 and with same image and same stock and all the rest settings are the same for that “variation” for all products in backend.

I have the same problem in Appearance –> Widget.

Is there somebody who can help me to resolve this problem?
