Can't create new customer after update

Hello to all I have a strange issue in my Dolibarr.

I had version 10 and upgraded with success to version 10.0.6.

I noticed that when I try to create a new third party (customer), when I press SAVE it just refreshes the page but nothing happens.

If I check for the new customer into the list, then i can not see it.

Anyone has any idea of what could be ?
