Пока цикл останавливается после первой итерации

Question

Я запускаю скрипт, который строит и отправляет письма клиентам, если текущая дата соответствует дате из базы данных.

Моя проблема заключается в том, что цикл в то время как останавливается после первой итерации и выводит следующее предупреждение:

Предупреждения: mysqli_stmt :: выборки() [MySQLi-stmt.fetch]: не удался выборка mysqli_stmt в FilePath по линии 17

Первая итерация работает безотказно и отправляет сообщение электронной почты правильно. Я вставив весь в то время как цикл ниже как я не уверен, где происходит ошибка ..
