Hi Veena,
Sorry to be unclear. I tried saving them in the childtheme/languages folder and it did not work. (not even sure if that suppose to work?) – I placed them in the parent /languages folder and it did work.
Is the languages folder ever gonna be replaced if an update comes out, normally it does right? As WordPress removes the folder and replaces the new one when it’s installing an update …
Hope this is more clear.
