Translation of the submenu.

[Panoulis64]

In the main menu of the forum, a submenu appears in the gallery and I want to translate it into Greek, but I can not find where it exists.
Can you tell me the route so I can find it?
Thanks.

*In the attachments I have a relevant photo, the point I am interested in.

It would be in the Themes/default/languages/modifications.english.php

You have then add the strings to modifications.greek.php
