14120	site-specific theme selection won't save in upgraded MU installs	andrea_r		"This only affects upgraded from wordpressmu installs, and not new or single WordPress upgraded installs.

Make sure you have some themes disabled under Super Admin -> Themes. 

Now go to Super Admin -> Sites and edit a site. On the right is a meta box called Site Themes. This will show a list of network-wide disabled themes, with checkboxes so you can enabled a theme for specific sites.

Tick the checkbox(es) and save. On refresh they are unchecked again and will not appear on the site's Appearance menu."	defect (bug)	closed	normal	3.0.1	Multisite		normal	fixed	has-patch
