Moodle исправить ошибки при интеграции плагина

При установке модуля Электронного деканата http://docs.deansoffice.ru/ru/%D0%97%D0%B0%D0%B3%D0%BB%D0%B0%D0%B2%D0%BD%D0%B0%D1%8F_%D1%81%D1%82%D1%80%D0%B0%D0%BD%D0%B8%D1%86%D0%B0 возникают ошибки (связано по большей части с тем, что модуль написан под старые версии php).
Часть ошибок уже мной поправлена, на данный момент остались критичные, с которыми я так и не смог разобраться в силу не полного понимания работы Moodle в целом либо синтаксические некритичныйе ошибки. Основная задача - в скорейшее время разобраться почему возникают критичные ошибки (хотя бы пару из них) и объяснить как их решить. В случае успешного сотрудничества - оплата сразу + дальнейшая разовая помощь мне в попытках все там поправить (с почасовай/сдельной оплатой).
