Exclusion List shows root server directory

[Roadsider]

This cannot be right. Why is this showing up? I can't get to the website directory to exclude anything within that.

If you have your WordPress installation setup to run in a different directory the plugin will show files from the WordPress Address (URL) and the Site Address (URL).

It will then backup the WP_CONTENT_DIR followed by what is returned by get_home_path() => https://github.com/WordPress/WordPress/blob/master/wp-admin/includes/file.php#L81

In your case it looks like this function is returning '/' for some reason. Is this what your document_root is set to in Apache?
