Dont create my new characters:

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY'' in C:\xampp\htdocs\pot\OTS_Player.php:187 Stack trace: #0 C:\xampp\htdocs\pot\OTS_Player.php(187): PDO->query('INSERT INTO `pl...') #1 C:\xampp\htdocs\accountmanagement.php(952): OTS_Player->save() #2 C:\xampp\htdocs\index.php(135): include('C:\xampp\htdocs...') #3 {main} thrown in C:\xampp\htdocs\pot\OTS_Player.php on line 187

Its like the php code dont change the id to create a new one.

I THINK I know what's wrong.
You have set more than one PRIMARY key in the table Players in your database
I think you may only have one primary key

You can't SET it. However a query (in gesior) is trying to do so. PRIMARY needs to be unique.
