Hi @maijavilkina,
I’m not definite about this but are you sure the user’s are not being created? I only ask because I think that when using the wp_create_user() function you need to pass it the plain text password, no need to create a hash. If I am right, the user is created but instead of ‘password’ being the password it is actually the has of that: ‘Juwufbfuahduhaf209r32’.
Also, you might want to consider using wp_insert_user() you can pass the first name, last name and display name to that which means you don’t need to create and separately update the user 🙂
I’m not sure either of these have anything to do with your issue, but the first one might 🙂 The user should still be created though!
