Hello turnermm,
Thank you for the fast answer.
Yes, that was my mistake.
But somehow I am not in the same directory with the Editor.
I can upload files but I cannot use them. The File Browser uploades them somewhere else.
Also I cannot see the other alredy uploaded files.
On the left of my screenshot you see the files already uploded a few days ago with the dokuwiki media manager.
With the ckgedit plugin I don't see those files. If I upload a file with the ckgedit plug in I see it with the file browser, but not with the mediamanager. Also I cannot link to the file because the file is not where it is supposed to be and where the path points to.
(I have a hoster with a Linux server)
