php - Codeigniter + HMVC is only requesting login_lang file ... all other module's lang files are not being loaded -

i made copy of working application, made changes modules @ point noticed language files not being loaded.

for example, @ login (myapp/login), file login_lang.php requested, , if not present (i renamed file not find it) error thrown.

other modules within app (myapp/dashboard) don't request corresponding language file (dashboard_lang.php) again, if rename login_lang.php other name, module throw "login_lang.php file not found" error.

i think modules requesting first file (login_lang.php)

i've gone thru lot of forums, questions, etc. unsuccessfully.

any ideas of causing behavior?

thanks in advance.

in language put module name first. can create language folder inside module lets modules => admin => language => en

modules => admin => language => en => dashboard_lang.php

$autoload['language'] = array('admin/dashboard'); 

or on controller

modules => admin => language => en => dashboard_lang.php

$this->lang->load('admin/dashboard', 'english'); 

with sub folder

modules => admin => language => en => common => dashboard_lang.php

$autoload['language'] = array('admin/common/dashboard'); 

or on controller

modules => admin => language => en => common => dashboard_lang.php

 $this->lang->load('admin/common/dashboard', 'english');
