Admin Bar & Dashboard Access Control

Hi, Having integrated my WP site with amember I noticed that if a member (expired or otherwise) was away of /wp-admin (highly unlikely but you never know) they could access the dashboard to the site, albeit with limited access to certain things. This plug in worked perfectly after installation as I tested it using ‘testuser’ log in details. Note: I had set plug in to redirect to main site on log in attempt BUT & here is the issue, when I then went to log in as myself, typing xxmysitexx.com/wp-admin it redirects me still. I went into dashboard using different browser & deleted the redirect option. & it still done it I can only assume that cookies stored after first test. I can clear cookies now I suppose, now I know it works. But I did think I would just mention this The page I need help with: [ log in to see the link]
