i will try, thanks

All translations strings need to be done via ossn_print()

You need to add translations in each file example ossn.de.php
https://github.com/opensource-socialnetwork/opensource-socialnetwork/blob/master/locale/ossn.de.php#LL40C1-L41C28

Example ossn.de.php for

  ossn_register_languages('de', array(
        'male' => 'männlich',
        'female' => 'weiblich',
         'other' => 'Other',
        ' fourthgender' => 'Forth Translation',
 ));

I mentioend this in my previous reply too, ossn.en.php

ossn_register_languages('en', array(
        'weiblich' => 'Something',
        'nonbinary' => 'Translation',
        'other' => 'Other',
        'unsure' => 'Unsure',                                   
));

How exactly do i have to do it?

how is the ossn_print recognizing the langauge selected by user?

This component already support translation

'options' => array(
 'male' => ossn_print('male'),
 'female' => ossn_print('female'),
 'other' => ossn_print('other') 
 'fourth_gender' => ossn_print('fourthgender')
 )

I need help to implement locale file for translation

So you’ll fix the extended member component?

Or do I just have to add you code to the locale file from extended member?

You need to add translation for values, problem doesn't relates to this component but the Extended member using values for translation.

ossn_register_languages('en', array(
        'weiblich' => 'Something',
        'nonbinary' => 'Translation',
        'other' => 'Other',
        'unsure' => 'Unsure',                                   
));

on profile it is working

but not with "site members"
