PHP - MYSQL Соединение Isuue

Question

Я использую XXAMP и пытаюсь добавить нового пользователя в базу данных. Но после заполнения формы в Register. php пользователь не добавляется в базу данных (phpmyadmin). У меня нет сообщений об ошибках, поэтому их очень сложно устранить.

Целью будет добавление нового пользователя в базу данных phpmyadmin на localhost: 8080. Спасибо.
