Test Compatibility of WooCommerce Extensions with Translation Loading Changes in WordPress 6.7

[Sourabh208]

WordPress 6.7 introduces updates to how translations are loaded. These changes may impact WooCommerce extensions that rely on localized strings. To ensure compatibility, we need to test all extensions to verify that translations load correctly without errors.

Developer advisory: Translation loading changes in WordPress 6.7

Steps to Test Extensions Compatibility with Translation Changes

1. Install WordPress 6.7.1, WooCommerce, and the WooCommerce extension(s) in a local environment with SSL enable.
2. Enable WP Debug mode.
3. Change the site language in Settings > General > Site Language to a non-English language with available translations.
4. Verify that translations load correctly in the WooCommerce admin settings and back-end areas.
5. Check the front-end functionality of the extension to ensure user-facing strings are translated properly.
6. Check the server and WordPress debug logs for errors related to translation loading.
7. Document any issues, errors, or log warnings in the below comment on this issue.
8. Expected Result: All strings are correctly translated and no errors are found in log or admin area.

Hello @Sourabh208,

I invested a lot of time testing various scenarios, but unfortunately, I wasn't able to reproduce the issue.

Environment

• WordPress: 6.7.1
• Active Theme: Twenty Twenty-Five (also tested with TT4 and Storefront)
• WooCommerce: 9.4.1 (also tested 9.5.1)
• Language: Tested on English and non-English languages
• PHP: 8.2.23 (also tried 8.1 and 8.3)
• Web Server: nginx
• Browser: Chrome 131.0.6778.204
• OS: GNU/Linux Debian
• Square: 4.8.4

As you can see, I encountered some deprecation dynamic properties messages. I also forced a USER_NOTICE error to confirm WordPress is properly outputting errors.

Do you have anything specific in your local environment that could help me replicate this? It's also unexpected for me that you're not seeing these deprecation warnings.

One option I can see is for you to export your local site, upload it to Google Drive, and share it with me. Alternatively, we could schedule a quick call after the holidays to troubleshoot this together. If we're in different time zones, I'm happy to adjust to yours.

Let me know if you have any other ideas or suggestions.

Thank you!
