Helped Luis with his problem with Montblanc's POS, No local setting found and Url error in Hachicko:
What i did was run the simplepos in the terminal to identify the cause of problem, check also the simplepos back configuration and add this table on the database.
 ALTER TABLE cy_daily_header ADD loyalty_acct_number varchar(40);
ALTER TABLE cy_suspend_header ADD loyalty_acct_number varchar(40);
ALTER TABLE pos_settings ADD hachiko_url VARCHAR(254);
