[deleted] do you now see the sitemap ?
Also is your sitemap also correctly generated by the Flagrow Sitemap extension ? It also doesn't generate an actual file and any
sitemap.xml file should be deleted.
So for everything to work you should have no
sitemap.xml files on the server, but the urls should work because they are answered directly via Flarum backend.
If it still doesn't work, maybe you can share your website url with us ?
