braekling on "[Plugin: WP-Piwik] Auto Config"

It may be a bug... but this depends on your settings. Are both sites using the same domain? Please compare how the pages are configured within Piwik.

You also can run the test script (see Settings -> WP-Piwik -> Support) to get further details. Of course, you can also post the results here, so I can have a look at them.

Of course, every WordPress admin is able to see your other sites created in Piwik if you are using a Piwik admin auth token to connect to Piwik. Even if WP-Piwik won't show the sites there, everybody who gets your auth token is able to access (and also to manage) your Piwik instance.

You have two choices to avoid this:

1. Only use a site specific auth token to connect to Piwik (i.e., create a user who is only allowed to access your blog and use this auth token).

2. Don't give the WordPress admin role to other users. Instead, choose a meaningful role or create a specific role for such users, so they can manage your blog without getting access to configuration details of your plugins.
