We're running 20.11.06 on our test site. In the staff interface searching, and editing a found record work fine. The problem occurs when I try to use authorities (any step of the process from searching, to looking at one, to editing one, or any method used to create a new biblio. authorities/authorities-home.pl authorities/ authorities-home.pl?op=do_search&type=intranet&authtypecode=&marclist=mainmainentry&and_or=and&excluding=&operator=contains&value=harmonica&orderby=HeadingAsc authorities/authorities.pl?authid=11041 cataloguing/addbooks.pl cataloguing/z3950_search.pl?biblionumber=&frameworkcode=Default cataloguing/addbiblio.pl?frameworkcode=BKS We can't find anything suspicious in the log files.
