WordPress MU

hi every body,
i have run a site by WPMU (version 1.5.1) and i wanna give an ability to my users to edit themes by them selves but the main theme does not change
i downloaded a plugin named (USER THEMES) but it wants theme-editor.php
how can i do that?
i mean where is this file in WPMU?
please help me

the theme editor has been taken out of wpmu a couple of version ago...

Users + Editing theme files = Wide open security problem.

Use the usertheme.php plugin files and edit theme-editor.php to close one of the holes. The main theme file is sent to the individual blog home for editing, leaving the admin file untouched. Make sure to provide valid html and css in the admin theme.

Just take care in granting access to the theme editor.

it didn't work my friend i have this plugin
and it copies themes to the users blog but when i wanna edit themes using themeeditor from MU 1.2.1 it says that not them was selected
and another point is that when userthem copies thems to them user folder no themes shown at themes page
please help me i need this ability

lunabyte, that's a good point. But, is there a way that just the admin/main site's blog owner can edit the theme in the dashboard? Have the developers considered that, or is that also a security risk?

As the site admin, use FTP.

That way, there is no chance of having some type of web based editing hacked.

Its a valid question. Not so much the developer but for when you hand the site over to the client and want to allow them to be able to do some basic updating/customising of their own.

It does not need to be applicable down to user level but FTP/SSH online editor is too much to ask.
