Why not keep it simple?

CMD:cc(pid, params[])
{
	#pragma unused params
	for(new cc = 0; cc < 250; cc++)
	{
		SCMToAll(COLOR_WHITE, " ");
	}

	new name[MAX_PLAYER_NAME + 1];
	GetPlayerName(playerid, name, sizeof(name));
	format(string, sizeof(string), "The chat has been cleared by {FF0000}%s", name);
	SCMToAll(COLOR_WHITE, string);
}

You were using first bracket wrong way around and you've missed quote mark after string formatting.
