After updating from Build 1226 to build 1238 there is an error message and a login is not possible. The forum is no longer accessible. In my test forum OAuth is enabled. For a new installation and deactivate OAuth error does not occur.

Catchable fatal error: Argument 3 passed to phpbb\auth\provider\db::__construct() must be an instance of phpbb\passwords\manager, instance of phpbb\request\request given, called in C:\xampp\htdocs\1238\phpbb\auth\provider\oauth\oauth.php on line 153 and defined in C:\xampp\htdocs\1238\phpbb\auth\provider\db.php on line 39
