[Résolu] Translator cannot find strings to translate even though detection is enabled

Background of the issue:
I am trying to translate strings on my website using WPML, but the string translation tool is not detecting any strings even though automatic detection is enabled. Link to a page where the issue can be seen: lien caché...&translation-priority=undefined

Symptoms:
The message "No strings found," indicating that no translatable strings were detected.

Questions:
Why is the string translation tool not detecting any strings?
How can I ensure that strings are detected for translation?
