Hi Stefan,
I hope you are well today and thank you for your question.
I saw in your recent update you made changes to the translation .pot-file and now all the translations that I have done are gone.
We have added some more strings in the POT file so line numbers of strings got changed.
Do I need to download the jevelin.pot again and start all over with the translation or do I just need to re-upload my .po and .mo files back to the server?
If you don’t want to translate updated strings and are satisfied with old translation then you just need to re-upload my .po and .mo files back to the server.
Can I also add them to the Child Theme so that I don’t lose them with every update again?
Yes you can, Just create a directory languages in your child theme root folder and add translation files in it.
Best regards,
Shufflehound team
