First of all: Thanks for this nice module.
So far it worked great, but I recently set up a new site, where I ran into some problems with the library browser.
The problem is, that in the media browser settings (as well as in the media-module-provided "add media" dialog) the media library is not shown.
On admin/config/media/browser I can only choose to activate "Upload" and "Web".
"Library" and "View Library" are missing.
Also, when adding media to an article, the only option/tab available is "Upload".
It is not possible, to reuse images already present on the server by browsing the library.
I already tried reinstalling the media module (Version 7.x-2.0-unstable7).
The plugins are present in the module folder (in media/includes/), and the file permissions are also ok.. but they just are not recognized.
Thanks for your help & best regards,
