I'm wondering that Drupal t() strings are not available for the translation.
Let me explain what I did. I'm going to make my site as multilingual (English & Dutch). English is my source language.
For this, I have added locale module and enabled English and Dutch language.
And then I wanted to show some multilingual text in the user profile edit form. Hence I put form alter and given some string inside t('My topics').
Then I went to /admin/config/regional/translate/translate this page to add a translation for my custom string "My topics". But it not available there.
Where did I'm going wrong?
I'm using - Drupal 7.54 - Enabled Drupal's core locale module - Entity Translation(7.x-1.0-beta6) - Internalization (7.x-1.17)
