Hi everyone, I tried to do a base migration from 3.20 to 17.11.06. The conversion of the database to the new schema and indexation has gone ok - everything works except the possibility of a full preview of the patron - after choosing one they receive such an error: Template process failed: undef error - DBIx::Class::Storage::DBI::_dbh_execute(): Table 'koha_biblio-main.club_enrollments' doesn't exist at /usr/share/koha/lib/Koha/Objects.pm line 269 I did two attempts and this problem appeared every time. System: Ubuntu 16.04LTS DataBase: MariaDB 10.0.34 Plack not enabled - when enable plack I get an error: Internal Server Error In the version of koha 17.11.05 there was no such error - the earlier attempt to migrate to this version was successful. I have a question about what I can do about it. Alternatively, how to withdrawal to an earlier version 17.11.05 to check whether this error can be invoked.
