Upon trying to check items out to a patron this message appears:

-- Software error:

I encountered exactly those same errors on my Koha 3.6.1. It seems the errors only appear when you upgrade the db from a previous version (3.2, in my case) of Koha to 3.6. I also got these errors when Koha is updating the database through the web installer: -- [Fri Dec 09 04:52:16 2011] updatedatabase.pl: DBD::mysql::db do failed: Duplicate column name 'privacy' at /home/koha/kohaclone/installer/data/mysql/updatedatabase.pl line 3997.

The script is attempting to create fields that are already in the tables, so I doubt you will see any problems." On Thu, Dec 15, 2011 at 3:22 AM, Perch <jp@pk.dy.fi> wrote: this

The item gets checked out (i.e. it appears in the list of items checked out to the client when you go return to the checkout page). The same happens with check in. The items get checked in, but Koha stops at the error message.

Similar error message appears when trying to add a new issue to an existing subscription. I think the problem might be related to error I received when updating the database to new Koha version (http://koha.1045719.n5.nabble.com/Database-update-errors-td5068234.html).

Any help here? We really really need to get this working.
