Hi, I installed Koha 3.6.0 in a Ubuntu Server 11.10. Everithing works. I create a Marc file of our previous system and imported ~86.000 records using Tools > Stage MARC records for import and Staged MARC record management. It's work. Then, I did not find the option to hide results in OPAC with no items. This option still exists? Then I export in MARC... clean the database and import again using Stage MARC records. But I did not Import with Staged MARC record management. This records are in the reservoir. I go to Cataloging > Search. I found a record in reservoir, but when I click in "Add biblio", I found this error: *Software error: All arguments must be MARC::Field objects at /usr/share/koha/intranet/cgi-bin/cataloguing/addbiblio.pl line 150* Can anyone help me?
