Most of the searching seems to indicate an issue with migrations, in this instance we are simply working through the recommended upgrades in the Admin panel / docker all on the same server.
I did see some indications there may be a mechanism for deleting images automatically and our logo file may have been removed because the clean up mechanism thought it was unused.
From my searches I have tried various rake commands to no avail.
Questions:
Is there a way to recover the image?
How do I re-upload the image to brand header component? There does not seem to be an upload function.
How do we prevent the image from being auto removed in the future?
Grazie @martym per le informazioni su come risolvere il problema. Abbiamo riscontrato un problema simile con la nostra intestazione. Ho anche notato che alcuni altri file non sono accessibili (errore 403), che sembrano essere immagini predefinite di Discourse (o dal tema Mint che stiamo utilizzando).
