Помогите найти ошибку в скрипте

Здравствуйте, есть скрипт обмена ссылками Linx для Joomla. Но в коде есть ошибка, которая заключается в том, что при добавлении больше чем 20 ссылок, должна появляться следующая страница, где будут расположены последующие ссылки. Страницы появляются, но при нажатии на ссылку выдается ошибка 404.

Подскажите если несложно в чем проблема. Если что то серьёзное, то назовите сумму за какую сможете исправить.

Спасибо за помощь.

Вот сам скрипт:
