Sorry, you are not allowed to access this page.

Running only this plugin on our testserver.
I am ADMIN of the site.

After installing and activating the plugin, i head over to “installed plugins” and click on the SETTINGS link below the plugin name.

I get a white screen with this error:

Sorry, you are not allowed to access this page.

From looking around the forum, it seems like I am not the only one with the same issue.
