WordPress Core
The WordPress Core section in Loco Translate lets you manage and translate the main language files for your WordPress installation.
Here, you can see all available languages, their translation progress, the number of strings, pending translations, and when each language file was last modified.
Language Overview

- Language: Lists all languages available for WordPress core translations (e.g., Armenian, Chinese, Dutch, English, French, German, Italian, etc.).
- Translation progress: Shows the percentage of translated strings for each language.
- Strings: The total number of translatable strings in each language file.
- Pending: Number of strings that still need translation.
- File info: The filename of the PO file for each language (e.g., en_AU.po).
- Last modified: When the translation file was last updated.
- Folder: Indicates where the translation file is stored (usually 'System').
Upload PO file
When uploading a PO file, make sure to name the file according to your region's language code. For example:
- For US English, use
en_US.po. - For French (France), use
fr_FR.po. - For German (Germany), use
de_DE.po.
This ensures that WordPress recognizes and applies the correct translations for your site's region.
