I am using Drupal commons. I am using I18n and other related modules for my website as it is created in English but is being used in French also. I am using translations provided. My issue is that I have string translations but for some strings, text is not being translated, although the translations are available in the drupal.
UPDATE After going through code, I found that this "Request Message" field is not a normal form field, but it is being rendered using
field_attach_form('og_membership', $og_membership, $form['membership_fields'], $form_state);
The issue is with this "field_attach_form()". Do ANYONE have any idea what can be done for this??
