Прерывистая служба недоступна ошибка в корзине покупок

Я строю корзину для покупок, и сейчас я работаю над системой категорий товаров. Я должен добавить категории из панели администратора, которая работает нормально.

Теперь, когда я хочу обновить категорию, страница продолжает загружаться и через 3-4 минуты она показывает, что service temporarily unavailable error в Mozilla Firefox и 404 error в хроме.

Когда связался с хостинг-провайдером, вот что он отправил по почте:

The issue that you are facing is mainly due to saturation of the number of fcgi processes allocated for your account. We allow 3 child process and for each child process, 256 worker processes. Once that limit is breached, you see that kind of error. However, those errors are auto-fixed once the number of processes reduce.

In order to fix the issue permanently, you need to optimize your codes or please go for VPS packages.
