I just love answering my own questions... After some trial and error I made a selective backup of the database; sudo mysqldump -p temp accountlines accountoffsets action_logs auth_header auth_subfield_structure auth_tag_structure auth_types biblio biblio_framework biblioitems borrowers branchcategories branches branchrelations class_sort_rules class_sources currency deletedbiblio deletedbiblioitems deletedborrowers deleteditems import_batches import_biblios import_records issues issuingrules items itemtypes statistics temp_upg_biblioitems_call_num userflags zebraqueue systempreferences z3950servers stopwords sessions reserves reserveconstraints repeatable_holidays printers categories > test5.sql And after setting up Koha again, and importing this backup with; sudo mysql -p koha < test5.sql it seems to work fine so far, even if I still get many errors from the updatedatabase.pl I hope it can help somebody, Marty --- On Mon, 11/15/10, Marty <ontariowolf64@yahoo.com> wrote: From: Marty <ontariowolf64@yahoo.com> Subject: [Koha] Cataloguing disappears after updatedatabase runs To: "koha koha" <koha@lists.katipo.co.nz> Received: Monday, November 15, 2010, 7:52 PM (Was: In koha-3.02.00 where is the cataloguing?) After installing koha 3.02.00.004 again, this time from scratch on my test box, everything works fine. However, after putting my backup database in, and it runs updatedatabase.pl it fails miserably (and that's also where my cataloguing page disappears, among other things) Backups are made with mysqldump, is there a way to restore my backup in the new version another way? Or any way where updatedatabase won't fail? I have tried other installs (3.02.005) but I keep having things disappear. See below for the errors. Thanks, Marty
