i18n: Translation files (.po) outdated — 261+ strings missing from shipped translations #173
Description
Summary
Translation (.po/.mo) files shipped with the plugin are outdated and missing 261+ strings compared to the current .pot template. This causes the admin UI to display English text even when WordPress is set to a non-English locale (e.g., Japanese).
All PHP strings are properly wrapped with WordPress i18n functions — the issue is that the .po files haven't been regenerated to match the current .pot.
Evidence
Screenshot context: WordPress admin set to Japanese locale, but SlimStat UI displays in English.
Strings visible in admin UI — all missing from ja.po

Translation file stats
| File | Strings | Status |
|---|---|---|
| wp-slimstat.pot | 1,439 | Current (2026-03-11) |
| wp-slimstat-ja.po | 1,178 | Outdated — missing 261 strings |
| wp-slimstat-ja.po untranslated | 755 / 1,178 | 64% empty even among included strings |
All other shipped .po files (de_DE, fr_FR, fa_IR, etc.) likely have the same gap.
Suggested Fix
- Regenerate all .po files from the current .pot:
for po in languages/wp-slimstat-*.po; do msgmerge --update "$po" languages/wp-slimstat.pot done
- Rebuild .mo files from updated .po files
- Consider enabling GlotPress / translate.wordpress.org for community-driven translations
