box message is different for Template_talk:Expand/fr than for Template_talk:Expand because no discussion page exists in FR (today). Involved code :
| fix = {{#ifexist:{{TALKPAGENAME}}|<translate><!--T:4--> More information might be found on the [[<tvar|1>{{TALKPAGENAME}}</>|talk page]].</translate>|}}
The discussion page should refer to the root page and not the translated page. --Christian 🇫🇷 FR (talk) 22:09, 18 March 2021 (UTC)
