Hello, I'm new to Koha and I haven't been able to import biblio in the catalog for a while now. Here is what I've done: I imported biblios using a .mrc file but those biblios only show up in the reservoir in the cataloguing search. Then I supposed I had to create 1 item for each biblio but still, searching in the catalogue finds nothing. Even after several days zebra doesn't update its database (Second question how can I update database automatically whenever I add a biblio). Finally, I used the command line koha-rebuild-zebra and... Miracle items are in the catalogue searching with keyword BUT those are empty: there is no data in it as if it didn't use biblios to fill them. Here are my questions: 1. Is it possible to show biblios instead of items ine the catalogue search? or automatically create one item of each? 2. how can I update database automatically whenever I add a biblio? Wiki says it's done every 20mins or so but after one week mine doesn't seem to work that way. 3.Most important: Why are my items empty??? when i try to modify them it either redirect me to a new item creation page or to an error page about additem.pl (Can't call method "fields" on an undefined value at /usr/share/koha/intranet/cgi-bin/cataloguing/additem.pl line 647.) Hope someone can help me. Regards
