When was the noble verse revealed: "Say, 'Is it other than Allah you order me to worship, O you ignorant ones?'" And what is the meaning of "the ignorant ones" in it?

The exact time of the revelation of the verse, "Say, 'Is it other than Allah that you order me to worship, O you ignorant ones?'" is not precisely determined, but it is likely Meccan. Commentators have mentioned reasons for its revelation, among them: the polytheists inviting the Prophet (peace be upon him) to worship their gods in exchange for them worshipping his God, or their offering him money and women in exchange for him ceasing to insult their gods, or their saying to him, "Are you misguiding your fathers and grandfathers, O Muhammad?"

The meaning of "the ignorant ones" in the verse refers to those who are ignorant of the clear indications of Allah's Oneness. They do not comprehend what these indications imply regarding the necessity of singling out Allah for worship, even though they are aware of the evidences themselves.
