You haven't run the database code.
It is failing to find the setting to say wether the site is enabled or disabled, defaulting to FALSE and trying to find the error message which is
also in the database.
I will hardcode an error message into the code if there is no setting showing.
Basically, all you need to do is run the database code provided in:
/database/1-tables.sql
/database/2-dummy_data.sql
