Hello!
My server is hide player list & When connecting to the server, the number of users is being displayed as'???'
but, where dynmap sidebar is announce player list. How can i hide sidebar player list?

You can disable the sidebar in the config, warning if you disable the sidebar you will disable the ability to switch maps. I recommend you disable player locations or disable players in the sidebar instead

I solve it
I modify map.js and Annotation it

	//var playersSection = SidebarUtils.createListSection(me.options['msg-players']);
	//me.playerlist = playersSection.content.addClass('playerlist');
	//playersSection.section.appendTo(panel);
	//me.playerfield = playersSection.legend;
	//me.sidebarSections.push(playersSection);
