 In case you run a migration that contained an error, migrate will not let you run other migrations on the same database. You will see an error like `Dirty database version 1. Fix and force version`, even when you fix the erred migration. This means your database was marked as 'dirty'.
 You need to investigate the migration error - was your migration applied partially, or was it not applied at all? Once you know, you should force your database to a version reflecting it's real state. You can do so with `force` command:
 ```
-migrate -path PATH_TO_YOUR_MIGRATIONS -database YOUR_DATBASE_URL force VERSION
+migrate -path PATH_TO_YOUR_MIGRATIONS -database YOUR_DATABASE_URL force VERSION
 ```
 Once you force the version and your migration was fixed, your database is 'clean' again and you can proceed with your migrations.
