Problems with the database

[andreamarucci]

Hello, I've a problem, maybe, with the db that's corrupt. THe customer deleted one category and all the products in that categories are now impossible to edit since when I try to assign another category, I got this message attached and I can't assign it to anything.

 

Can someone please suggest what can I do to fix this?

 

Thanks!

for 500 error, enable PrestaShop debug mode, then you have good idea of underlying php error.
