You can’t.
And the reason you can’t is that plugins & themes are shared across the entire network. If you allow theme editing and User A edits TwentyTen, all other users with that theme will get the same edits.
Plugin editing? That’s just asking for the entire site to go down.
If your users absolutely need to edit plugins and themes, give them separate installs.
i understand all the risks. i just want to know how to do it. i read on another post that it is possible but then they described the dangers of it instead of showing how.
You’d need to use a capability manager plugin (like capsman) to give blog admins the “edit_themes” capability. However, as Andrea said, it can quickly lead to chaos for your MultiSite install if you do this.
thanx for the solution i will test it. any way i will not enable the editing on a working site. i made a portable wp installation using XAMPP in which solved my users requirements in editing themes.
