# Plugin incompatibility: Shiptastic

 * Hello there,
 * I am reaching out regarding a language loading issue with the **Shiptastic** 
   plugin when used alongside **Polylang Pro** and **Polylang for WooCommerce**.
 * Customer emails generated by Shiptastic and the Shiptastic admin interface are
   currently displaying in **English**, even though the entire website, WordPress
   site language, and admin user profiles are configured to standard **German** (`
   de_DE`). It does not matter if I select German, English or all languages (via
   your button in the admin bar) in the admin area.
 * This issue started a while ago; previously, everything rendered correctly in 
   German. All other areas of the site and all standard WooCommerce emails continue
   to display in German without any issues.
 * I have already performed several tests to isolate the root cause:
    - **Language Settings:** Confirmed that both the main site language and my user
      profile language are explicitly set to standard German (no formal, Swiss, 
      or Austrian variants).
    - **Cross-site Comparison:** On a separate website that does not use Polylang,
      Shiptastic works flawlessly in German.
    - **Staging Test & Conflict Isolation:** I cloned the site to a staging environment
      for testing. Deactivating both **Polylang Pro** and **Polylang for WooCommerce**
      immediately resolves the issue, restoring Shiptastic’s emails and admin area
      to German.
 * It appears there is an interaction issue between Polylang’s translation/locale
   loading and Shiptastic’s text domain.
 * What steps can I take to troubleshoot this further or fix the language fallback?
   Would specific logging or debug hooks help pinpoint where the text domain loading
   is being bypassed?
 * Kind regards,
 * Florian
