How to translate footer text?

Hi
Have you a wpml-config.xml on your theme directory? If yes, have you in this file a footer option?
Do you use a child theme?

Yes, I have wpml-config.xml in my theme’s files, but there is no footer option in it.

And yes, I’m using a child theme.

Could you provide a screenshot of where you have filed your link in your admin side?
You can upload them it https://snag.gy and link to it here.

I just manually inserted the link code into the footer.php file of my child theme.

I have already solved this problem. The solution was to create a functions.php file in my child theme and add the following code into it:

<?php
    if(function_exists('pll_register_string')) pll_register_string('Footer Text', '&copy; 2015 – Veronika Madudova &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <strong><a href="https://quantasha.com/de/impressum/">Impressum</a></strong>', 'Quantasha');
?>
