Добрый день.
Указал для пункта меню CSS-класс "custommycab".
В дополнительных стилях прописал
.cuctommycab {
color:blue;
}
Итог - конечно же, ничего не работает, цвет не поменялся.
Запустил инспектор в браузере, вот код элемента:

Мало чего понимаю, но стараюсь, вчера до 3х часов ночи сидел - ничего не получалось. Нужно изменить цвет только пункта меню "menu-item-617".
Помогите пожалуйста.
