Currently when contributor users inside our enterprise wiki 2013 try to add a new web part to a wiki page, they will get the following error:-
A Web Part or Web Form Control on this Page cannot be displayed or imported. You don't have Add and Customize Pages permissions required to perform this action.
I read that I can grant them the following:-
But it seems that this is too much permission in my case, because it will allow users to edit the web site using an editor. So is there a permission level which only allow contributor users to add web parts to the page without any extra permissions ?
Thanks
