I can’t get to pages in the Admin that use Dir/file.php

This mainly relates to plugins as they are the only ones that do this, but I have 2 plugins that add a tab to the Options page of the Admin. They format the links like this:

https://www.website.com/wp-admin/options-general.php?page=BAStats/BAStats.php
https://www.website.com/wp-admin/options-general.php?page=SK2/spam_karma_2_plugin.php

Notice how they have a folder/directory before the actual page name as that is where the file is inside the plugins folder.

For whatever reason, when I go to those pages, it just shows the regular WP Admin interface but no content…no options for either of those plugins.

Any ideas?
