https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=36491 --- Comment #2 from Mike G <it.manager@hope.edu.kh> --- Thanks for the reply. I've checked the calendar and notices, all seems ok. Here are some entries from the plack-error log. The DB connection error baffles me as the other functions querying the database is fine. DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: DBI connect('database=koha_library;host=localhost;port=3306','koha_library',...) failed: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) at /usr/share/koha/lib/Koha/Database.pm line 91. at /usr/share/koha/lib/C4/Context.pm line 669 C4::Languages::language_get_description(): DBI Exception: DBD::mysql::st execute failed: Lost connection to MySQL server during query at /usr/share/koha/lib/C4/Languages.pm line 368 DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Unknown column 'me.patron_id' in 'field list' at /usr/share/koha/lib/Koha/Objects.pm line 317 -- You are receiving this mail because: You are watching all bug changes.

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=36491 --- Comment #4 from Mike G <it.manager@hope.edu.kh> --- It turns out this was the issue: DBIx::Class::Storage::DBI::_dbh_execute(): DBI Exception: DBD::mysql::st execute failed: Unknown column 'me.patron_id' in 'field list' at /usr/share/koha/lib/Koha/Objects.pm line 317 The XML version of the schema (https://schema.koha-community.org/23_11/) helped figure out what objects should have patron_id. I found the bookings table was missing columns, which was then able to be re-created from the schema. I'm not sure what steps from the upgrade caused it, or if this was the best route to fix it. Regardless, I figured I'd share in case other run into it. Thanks for the help, cheers! -- You are receiving this mail because: You are watching all bug changes. You are the assignee for the bug.
