On Trac 0.11.3 with python 2.5, I have got the following error :

AttributeError: Cannot find an implementation of the "IPermissionStore" interface named "SuperUserPlugin".  Please update the option trac.permission_store in trac.ini.

The plugin was installed with :

easy_install http://trac-hacks.org/svn/superuserplugin

And the trac.ini modified as mentioned in the wiki.

Looks like the plugin is not correctly enabled... Try enabling the plugin:

tracsuperuser.* = enabled

without changing the permission store (avoid the following change):

permission_store = SuperUserPlugin

and check the plugin is listed and enabled in the trac admin.

If not, please include the output of the easy_install command. Also, did you try restarting the web server?
