Wenn ich versuche, das HTML von jedem beliebigen Beitrag neu zu erstellen, erhalte ich einen Fehler 500:

Helfen diese Informationen weiter?
Ich tue, was ich kann, um diese Beiträge zu reparieren, aber ich beginne zu glauben, dass dies etwas mit Discourse selbst zu tun hat und nicht mit etwas auf meiner Seite, oder? 
Edit: Siehe den automatisch verlinkten Beitrag unten.
Problem gelöst:
Jetzt muss ich nur noch alle meine Beiträge neu erstellen. 
Noch eine Edit:
Das hätte sicher funktioniert, und zwar für Bilder, die noch ihre alte einfache URL haben, aber:
-
Da alle alten, defekten Imageshack-Links durch gültige Bilder ersetzt wurden, die von Imageshack selbst eine ukrainische Flagge anzeigen, wurden sie automatisch auf Discourse hochgeladen, wodurch sich ihre URL in einen lokalen Markdown-Bildlink geändert hat.
-
Glücklicherweise wurden alle diese Flaggen mit identischen Links auf Discourse hochgeladen (
in meinem Fall – übrigens hervorragendes Verhalten von Discourse
), was bedeutet, dass sie sehr einfach zu finden und zu entfernen/ersetzen sind. 
Ich schreibe dies nur, um Leute zu informieren, die nach einer Migration auf dasselbe Problem stoßen könnten wie ich.
