This thread is resolved. Here is a description of the problem and solution.
Problem: The client was experiencing an issue where the navigation links in the Divi Builder blog layout were not translating correctly. Despite translating the Dutch words for 'next' and 'previous' into English using String Translation and translating the module, the English blogs still displayed the Dutch words 'Vorige' and 'Volgende'. Solution: The navigation link texts were coming from a custom body template created for posts in Divi > Theme Builder. The template can be translated by going to WPML > Translation Management and using the search filter to find the 'Body Template' post type then translating the correct template. After translating the template, the issue was resolved.
For blogs on the mentioned website I use the Divi builder.
This blog layout contains a blog navigation module to link to next and previous texts.
I have translated the Dutch words for next and previous into English via and String Translation and by translating the module but in the English blogs I still see Vorige and Volgende (the Dutch words for Previous and for Next).
I would need to request temporary access (WP-Admin and FTP) to investigate the issue further. Preferably to a test site where the problem has been replicated.
Your answer will be private, meaning only you and I can access it.
❌ Please backup your database and website first❌
✙ I would need your permission to de-activate and re-activate the Plugins and change configurations on the site. This is also a reason the backup is critical.
If you don't see the form below, please don't add your credentials as they will be publicly exposed: hidden link
The plugin will create a package file that you can download then upload again to Google Drive or Dropbox and share the download link in the next reply which I have marked as private. Then I’ll escalate this issue to our developers for further investigation.
Alternatively, you can grant me permission to install the plugin so I can create the copy from my end.
I imported the site copy locally to do more tests and found that the navigation links come from a custom body template created for posts in Divi > Theme builder.
So we were checking the wrong one, please go to WPML > Translation Management and use the search filter to find the "Body Template" post type and translate the one with ID: 10212
Once I translated the template the issue was resolved as you see in the attached screenshot.
