[Koha] Koha offline circulation

Hello! I have a koc file. When downloading, I get the following message: "Your file was uploaded. Once all files are uploaded, please process them in pending offline circulation actions. Upload another KOC file View pending offline circulation actions" Do I understand correctly that the file is uploaded? If I follow the link /cgi-bin/koha/offline_circ/list.pl then "Gateway Timeout" If I follow the link /cgi-bin/koha/circ/offline.pl then "Offline circulation disabled Your browser is not compatible with the built-in offline circulation tool." I use Microsoft Edge and Google Chrome. Koha 22.11.05 AllowOfflineCirculation - Enable What am I doing wrong? Good Luck! Igor A. Sychev Tomsk Polytechnic University https://lib.tpu.ru
