Как исправить преобразование PDF с dhtml2pdf?

Я использую Dhtml2pdf создать автоматический pdf для сайта https://www.iusefaith.com/en-101. До недавнего времени он успешно генерировал pdf-файлы, после того как я внес целый ряд изменений на веб-сайт, и теперь я больше не могу генерировать pdf-файлы. Я не могу сказать, что не так

Я получаю следующую ошибку:

Пожалуйста, что может означать эта ошибка и как ее исправить?
