Hi, i just installed koha but i cant get it to work.
On my website i get an Internal Server Error, Looking in plack-error.log:
DBD::mysql::st execute failed: Table 'koha_artifacts.systempreferences' doesn't exist at /usr/share/koha/lib/Koha/Database.pm line 152.
DBIx::Class::Storage::DBI::_dbh_execute(): Table 'koha_artifacts.library_groups' doesn't exist at /usr/share/koha/lib/Koha/Objects.pm line 399

The Database exists but is empty. All i can find on this problem is outdated it seems.
Hoping someone can guide me in the right direction.
Thanks.
