When a post/page (both, I think) is generated, the resulting og:url contains an extra forward slash, meaning an invalid URL.

For instance, on https://my-notes.dragas.net/about/, the og:url string is <meta property="og:url" content="https://my-notes.dragas.net//about/">.

I would have expected it to be <meta property="og:url" content="https://my-notes.dragas.net/about/">, with one, not two, forward slashes between the site_url and the page_url.

(Using your instance as an example, to rule it being a config issue on my side!)

I have edited my templates/header.html file, to change <meta property="og:url" content="{{site_url}}/{{page_url}}"> to <meta property="og:url" content="{{site_url}}{{page_url}}">. This has fixed it, but I don't know if this is the best way of fixing it.

(Although the URL is invalid, it does not appear to impact display on Mastodon, but I do not understand why there is no impact.)
