Steps to reproduce: 1. Navigate to a biblio with available items (ie https://kodevsod-intra.dev.imcode.com/cgi-bin/koha/catalogue/detail.pl?biblionumber=3296381) 2. Check boxes for två available items 3. Click "[U+1F5D1] Delete selected items" 4. Batch item deletion view is loaded. Click button "Delete selected items" 5. System presents text "0 item(s) deleted" Expected result: 2 item(s) deleted.
I don't recreate on master. Which exact version of Koha are you using? The latest 20.05.x (20.05.06)? Do you see an error in the Koha log files?
I think that the problem occurred due to a misconfiguration in our environment. Closing the bug report.
