Configuration
Detecting target language
From TYPO3 11.5 LTS on the detection of the target language works as following:
- Set up DeepL Translation language in SiteConfiguration * Target languages detected from DeepL will only appear
- Check hreflang against DeepL supported languages * Needed for detecting EN-GB, EN-US, PT-PT or PT-BR
- Fallback to Language ISO code
If none of these match against DeepL API, translation for this language is disabled for usage within DeepL. Translation buttons and dropdowns respect this setting.
