I’m having this problem as well, and am on the most current version of the plugin having just installed it for the first time today. I’m the admin of the site as well.
The plugin displays the setting of the page if you have edit_plugin rights, http://codex.wordpress.org/Roles_and_Capabilities#edit_plugins
Right, and as admin, I have all rights and do not have this problem with any other plugin.
That’s strange, can you mail me at ajmatharu[at]gmail[dot]com
Same problem here. I’ve downgraded to the old plugin version, and it seems to be working fine.
