Сударь!
Вам вряд ли сможет помочь это сообщество магов и чародеев, ибо код ваш в части приведенной ошибки безупречен...
Либо Вы чего то не договариваете, либо код не соответствует действительному.

PS Столько писал, а опередили.

Кинул код. Я подсчитал количество открывающих и закрывающих фигурных и обычных скобок -- количества совпадают. Я уже удалил все строки из этого файла, он занимает 0 байт, НО ошибка осталась и по-прежнему на 48-й строке.

Видимо не тот скрипт ты правишь, раз ничего не изменилось.

Ну тот, я уверен и проверял неоднократно ))
