How can I translate this theme ?

Here’s what you need to do to translate the theme.

1. Inside the package that you downloaded from themeforest there is a “language” folder, with “en_EN.mo” and “en_EN.po” files, along with other languages.
2. Make a copy and rename them to “xx_XX.mo”, “xx_XX.po”, where “xx” is the abreviation of your language. Click here to find a list of country/language codes.
3. Using poEdit you can translate from English to your own language;
4. Copy the two translated files (“xx_XX.mo”, “xx_XX.po”) inside the theme’s root folder: ”/themes/duotive-three”.
5. Open up “wp-config.php” file from your wordpress root installation folder and
6. Search for this line:

define ('WPLANG', '');

and replace it with this one:

define ('WPLANG', 'xx_XX');

And that’s it!
