That appears to have broken. \r\n\r\nie. `doc/users/faq/troubleshooting_faq.rst` has a `.. redirect-from:: /faq/troubleshooting_faq` which is _supposed_ to make a file https://matplotlib.org/devdocs/faq/troubleshooting_faq.html that redirects to https://matplotlib.org/devdocs/users/faq/troubleshooting_faq.html  However that file is not being created and so far as I can see no error messages are being emitted.  \r\n\r\nThis is loaded from `doc/sphinxext/redirect_from.py`\n\n### Suggested improvement\n\nThis should be fixed\n\n### Matplotlib Version\n\nmain","author":{"url":"https://github.com/jklymak","@type":"Person","name":"jklymak"},"datePublished":"2021-12-07T07:53:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":5},"url":"https://github.com/21876/matplotlib/issues/21876"}
