As the old setup in 1.7 seems to make problems I set up a new site in version 2.0 which went flawlessly. Finally uploaded a gedcom file with the option to discard the path information to mediafiles
Everything seems OK except I ended up with 404 in the Icons where the images should appear.
When in Person I open Tab multimedia I see the 404 on the left and a path media/Picturename.jpg. I uploaded the all the jpgs with identical names into this media directory bit this did not help. When I upload a single jpg anew it is there to the right after all the 404 icons. I cannot find a possibility to delete these (empty) images, only add or rearrange. Where may it be hidden?
I got it. Your message was helpful. I realised that a file in the /media directory has no path statement. If it has one, it is in a subdirectory of /media. Therefore a made 2 subdirectories /media/media and /media/Bilder copied in both all the jpg-files and now the 404 disappeared.
Now there is also a delete button functioning
