I install the plugin at seems it works fine as I can activate it on the plugins page. The problems appears when I want to find the settings page so I can fiddle with it. It is nowhere to be found, the items are not added to my menu at the left side of my admin-content.
This happens with other plugins too, by the way. I hope someone has a solution - it's like switch has been changed to avoid making my admin profile having access.
No WP Role-secondary plugin installed.
