Ковыряю сейчас самописную CMS, у нее ужасная панель администрирования, пока искал, как добавить созданную страницу в левое меню с помощью этой панели умудрился словить ошибку, на каждой странице где заголовок подтягивается с БД ошибка:
Warning: Invalid argument supplied for foreach() in /home/xx-xxx.ru/docs/lib/kernel.lib.php(160) : eval()'d code on line 64

Вот код этого самого ядра (жирным выделил 64 и 160 строки). Почему он на каждой странице генерит эту ошибку? В базе вроде ко все страницам title прописан.
