Hi Marcel, Thanks for your reply, we appreciate it. We are/were not using plugins, but just for testing I enabled the koha plugins system. Alas, it does not make any difference. When adding a new book to the catalogue, searching for subject authorities still gives no results, with these errors:

Anyone other ideas? MJ
