Will All Translations lost after theme update ?
If you are updating the Aryan theme and exact core plugin then YES your all translation done will be lost
So to avoid this loss you PLEASE ALWAYS BACK UP BEFORE UPGRADING. WE ARE NOT RESPONSIBLE FOR ANY LOSS.
Normally a WordPress theme requires that you use.PO and.MO files in the /languages directory of the theme.
Your Languages folder Theme path is :
Your Plugin language file path is :
Directly download your .po .mo files from there to a safe location before updating the theme.
After the theme and plugin are updated you can restore the .po and .mo file only to get your all translations back.
