あなたのライブサイトに問題があってデータベースに関連していれば、そのテーブルのIDに自動インクリメントが与えられていると思いますので、問題ありません。そうでなければ、0の重複エントリが表示されません。 – Exprator

increments()はあなたのためには機能していないようです。

Intタイプの列が作成され、auto_incrementという制約で作成できるので、unsignedInteger()を試すことができます。ちょうど周りのincrements()と同じです。以下のようにコードを書く必要があります。

ここ 
$table->unsignedInteger('id', true);

unsignedInteger()列の名前のためのstringとして第一引数を取り、AUTO_INCREMENTのためbooleanとして第二引数。これを試して、それが動作するかどうかお知らせください。
