When I used fask-track to check an IP, I had a bug and my fast-tracking was successful. So, what's wrong with my back-track? I tried reinstalling it but I still have the same bug:

msf > load db_sqlite3[*] Successfully loaded plugin: db_sqlite3
msf > db_destroy pentest
[-] Error while running command db_destroy: No such file or directory - pentest
