Hi We configured Koha to upload files, e. g. a PDF file is uploaded onto thehost running Koha via MARC field 856 $u: first selected, then uploaded, then chosen, so field 856 $u is filled with the following: /cgi-bin/koha/opac-retrieve-file.pl?id=5228ccd12bb0d5f002c804effe0680fe The PDF file then is visible in table "uploaded_files" as well as in directory "/var/lib/koha/<instancename>/uploads/koha_upload". In the OPAC when clicking on link "Click here to access online" the file is showing up all right. When clicking the respective link in the staff client, instead of the file there appears a white screen saying "not found". We have tested this in Koha 18.11 and 19.05. Is there something more to configure or is this maybe a bug? Best wishes: Michael -- Geschäftsführer · Diplombibliothekar BBS, Informatiker eidg.
