I am able to login to the admin control panel the first time and when I logout and login again it get this message:
There has been an error processing your request SQLSTATE: Integrity constraint violation: 1062 Duplicate entry '0' for key 'PRIMARY', query was:
INSERT INTO `admin_user_session` (`session_id`, `user_id`, `status`, `ip`) VALUES (?, ?, ?, ?)
But this works again when I get the empty
ADMIN_USER_SESSION table in PHPMyAdmin.
