• Themes are multilingual ready.
• Find .pot file at its default location.
  Location: Theme folder / languages / .pot

Step 1:

Edit .pot file ( add your translations) and generate a .po / .mo file for your language

How to Edit .pot file?

Step 2:

Upload these both .mo/.po files for your language, in Child Theme inside folder named as languages.

So .mo/.po File Upload Location will be:
Child Theme folder / languages / es_MX.po and es_MX.mo ( for Spanish (Mexico) language )

What is Child theme?

Step 3:

Add below function in child theme’s functions.php and save.
Child theme contains this functions.php file by default.

// Load translation files from child theme instead of the parent theme
function my_child_theme_locale() {
    load_child_theme_textdomain( 'vrukshagra', get_stylesheet_directory() . '/languages' );
}
add_action( 'after_setup_theme', 'my_child_theme_locale' );

• That’s all. Frontend will show translated text.

• Never add your .po/.mo files in main theme.
• You will loose these files on theme update.
• To avoid this, always use child theme.
• Better way to add these files is in child theme at the same location.
  Location: Child Theme folder / languages / es_MX.po and es_MX.mo ( for Spanish (Mexico) language )
