Hello,
I'm getting a really weird issue, basically if i create a new product, I can't enable combinations, it's simple:
1. Click on "product with combinations" and save product:
2. Reload the page and simple product is marked.
I've tested with chrome, firefox, edge and Safari, unable to activate.
I've tried to enable dev mode, but nothing strange happens. Tested also on browser network tab and I can see 200 POST but if I reload, nothing happens.
In the database, the product type is still "blank"
Any help? Obviously, combinations are enabled in performance tab
