Problem:
Plugin strings not translating after WPML default language change.

Solution:
Delete and recreate the translation strings in the WordPress admin dashboard, under WPML → Translations.

• In WPML → Translations, find the string - you can select domain of your plugin in the "Select strings within domain:" drop-down and use the "Search for:" field and search for part of the string to be translated
• Select all occurrences of the string and click "Delete selected strings" button - before this please copy the existing translations and save them somewhere for the later step
• At the bottom of the same page, in "Auto register strings for translation", activate the "Look for strings while pages are rendered" checkbox
• Reload the front end where plugin is active - plugin code should execute when the page is refreshed
• Go back to WPML → Translations, clear the "Look for strings while pages are rendered" checkbox, and perform the same search for the string again, it should show up on the list as "Not translated"
• Insert your saved translation from step 2, save, mark "translation is complete"

The translated string should now show up on the front end.
