Steps to reproduce
On a fresh installation and deployment of MediaWiki, navigate to the main page.
- Url of "Help" link in the sidebar is https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Contents
- Url of "User guide" link in the main page's body points to https://meta.wikimedia.org/wiki/Help:Contents/fr
Since the user guide on meta.wikimedia.org is being moved to mediawiki.org, the link in the main page's default content should point to the new location.
This issue has been noticed on a french language installation.
