- Located the .po file in folder /languages.
- Open the file with POEdit and translate the texts into your preferred language.
- When complete, you’ll want to save the file twice, as two separate files – a .po file and a .mo file. When you save the files, you must name them according to your language code. Find a list of language codes at WordPress in your Language. As an example, the language code for English is en_EN, so you would save the translated files as en_EN.po first, then en_EN.mo.
- When that’s done, simply upload the files to your theme folder.
Codestyling Localization is a good alternative for POEdit. It also works with .po/.mo files and is very easy to use.
