Ошибки загрузки файла BlueImp jQuery и ошибки ModSecurity

Я получаю периодические ошибки при пакетной загрузке с использованием BlueImp. Я использовал этот же код / ​​config на других машинах LAMP без проблем.

В течение часа моя рабочая пакетная загрузка с использованием BlueImp перешла от принятия любого файла, который я бросил к нему, к выдаче ошибок ModSecurity при каждой загрузке. Я связался с хостом, чтобы узнать, помечен ли мой IP-адрес или что-то в этом роде.

Учитывая, что задействованный код BlueImp огромен, я не публикую весь свой код с этим, только инициализацию из UploadHandler.php.

Кто-нибудь сталкивался с этим раньше, или если у кого-то есть совет относительно первых шагов для отладки этого?

Ошибки:
