How to avoid losing your translations when the theme or plugin is updated

A simple way that allows you to keep your translations and prevent them to be overridden is to create a copy of translation file in wp-content/languages

Make sure you create the following folder structure:

wp-content
– languages
– – plugins
– – – plugin-name-de_DE.po
– – – plugin-name-de_DE.mo
– – themes
– – – theme-name-de_DE.po
– – – theme-name-de_DE.mo
