Implementing another language before installation on ImpressPages 4.2.7 -

i tried implement default turkish language before installation on version 4.2.7:

/install/plugin/install/sql/data.sql

insert `ip_language` (`abbreviation`, `title`, `languageorder`, `isvisible`, `url`, `code`) values ('tr', 'türkçe', 1, 1, '', 'tr');

after installation next error:

fatal error: class '\ip\internal\translations\translator' not found in /home/***/public_html/test/ip/servicelocator.php on line 257

it working same method on version 4.2.5 doesnt work in version. changes on new version? missing?

i tried following:

insert `ip_language` (`abbreviation`, `title`, `languageorder`, `isvisible`, `url`, `code`) values ('en', 'english', 1, 1, '', 'en'), ('tr', 'türkçe', 1, 2, 'tr', 'tr');

installation success when move turkish language first, getting same error.

by way, these method works perfect on localhost doest work in live server.
