Hi, you probably changed the 999 field where Koha stores the biblionumber and biblioitemnumber - you need to restore this configuration. Maybe you still have an unchanged framework where you could copy from? Katrin On 28.02.2018 06:21, Ma. Victoria H. Silva-Manuel wrote:

Hi.

I'm getting this message:

software error No biblionumber tag for framework /usr/share/koha/lib/C4/Biblio.pm line 3013.

I edited some fields in 900s. What field should I restore to solve this problem.

Thanks
