I use a custom domain on Github pages, which is managed via Cloudflare. This seems to break Logseq Publish. The page was blank until I went into index.html and manually edited all the URLs (for the related javascript and css files) to the full URL. Then the site started working. It would be great if I could just add this root domain as an attribute so it was done automatically.
I suppose it would work best if it was in a separate document. That way one could still test the published graph locally, and that document wouldn’t be over-written when uploading to github.
