The module Kit Online needs to send a check to the mail for payment of the order.
1) At first, when trying to configure, it caused an SQLSTATE[42S22] error: Column not found: 1054.
2) Added the required column in the database, it solved the problem and I was able to go to the module settings.
However, it does not send anything, that is, it does not work as it should.
Maybe someone came across this?
