I tried all three possibilities of the English versions. In all attempts I get the error message in the user table.
Some errors occurred while populating the database: Table '123_name.jos_usergroups' doesn't exist SQL=-- -- Zrzut danych tabeli `jos_usergroups` -- INSERT INTO `jos_usergroups` (`id`, `parent_id`, `lft`, `rgt`, `title`) VALUES (1, 0, 1, 20, 'Public'), (2, 1, 6, 17, 'Registered'), (3, 2, 7, 14, 'Author'), (4, 3, 8, 11, 'Editor'), (5, 4, 9, 10, 'Publisher'), (6, 1, 2, 5, 'Manager'), (7, 6, 3, 4, 'Administrator'), (8, 1, 18, 19, 'Super Users')
