Problem: The client was experiencing an issue where strings translated using the
__('...');
function were not translating correctly for some languages, despite working previously. The issue was observed on a live site, while a local development site with outdated plugins did not exhibit the problem. Solution: We first confirmed that the client was using the gettext method for adding code inside their theme and translating strings via WPML > String Translation. We then suggested regenerating custom MO files from the WPML > Support > Troubleshooting page. Upon further investigation, we discovered that the client's theme was missing the text domain definition in the style.css file. After adding the required text domain and rescanning the theme's strings, we removed and re-translated a specific string to ensure WPML generated a fresh translation file, resolving the issue.
If this solution does not apply to your case, or if it seems outdated, we recommend checking the related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should the problem persist, please open a new support ticket.
