Perfectible with WordPress 3.6

The plugin prevent the add media in post edit page to work.
It does the same thing on the screen settings on the same page.
When i disabe the plugin, both buttons works.
Every plugins with private features i have testes have the same problem.
Many are discontinued, is it possible to fix yours ?
Furthermore i have noticed that we can access medias directly, is it possible to be redirected to the login page too ?
It’s not critical because we have to know the exact path and name but with this security the plugin will be closed to the the perfection.
Thank you very much in advance
