Moving this thread to AEM Forms topic so to have better continental experts have a look at this.
I tried that last week....Step 8 didn't have a "Start". I tried to work around it a bit, but it's confusing, and never got the translation working. My understanding was that the (english) page should be exported to a file, where the english text becomes keys to the french translations.
Did you change the translation property Translation Method from Human to Automated? If you don't you won't see a start you'll see import/export/rename.
My co-worker figured *something* out.
1. Use /libs/cq/i18n/translator.html to define the text for your URL(s)
2. Add ?wcmmode=disabled&afAcceptLang=fr to your URL, and the text just translates.
I think the first time I tried this, I wasn't look at the right URL in the list provided by translator.html
Thanks for the help
