Hi Kamil The general consensus was that it is "wrong version of DBIx::Class" thanks to Chris Cormack and "Most important is what Linux distribution and version you're running on. If your kernel and Perl versions are this old, I'm going to hazard a guess it's a pretty old one. … My expectation would be that the version of DBIx::Class you have installed is lower than the one required by Koha. How this is fixed depends totally on what distribution/version you're running and how the modules have been installed. -- thanks to Robin Shea". I have passed the message on to our support people but they haven't fixed it yet and I don't have permission.
