Ok the only difference I’m seeing between my site & Discourse is the following:
Inside a topic page I have :
<meta property="og:url" content="http://www.manga-sekai.com/" />
When Discourse has this :
<meta property="og:url" content="https://meta.discourse.org/t/sharing-links-on-facebook-doesnt-get-the-title-of-topic-in-rtl-languages/35852/2" />
og:url tells Facebook to scrap exactly this url. How do I get the meta dynamic ? Any idea?
