:: Sorry to trouble you again, but in ru:Выпадение прямой кишки#Классификация стадий заболевания, there is yet another problem with the captions. The bold red error message in there means "Error in expression. Unexpected operator <" in English. ru:Ясенево (район Москвы) works fine, and it probably worked fine before since both parameters height and width are specified in the gallery template in that article.
