I need a child version to update the theme and I don’t have much experience with this, so I did the test version of Child theme at the less important address b2b.lepa-darila.si.
I pressed up-date and the same problem occurred.
I ran over the Loco Translate settings and lost what I did.
It can be helped that on the main page lepa-darila.si I have correctly set Child theme, where we will have preserved word translations
