After server migration the images in posts aren't downloadable anymore

I took a look at @Bryanpwo’s forum and couldn’t see any obvious reason for which the Lightbox wouldn’t work.

The issue is acknowledged though:

Lightbox not working on Discourse

We’ve seen this happen intermittently and we are looking at what could be the cause. We need a consistent reproduction of this scenario more than once with steps one can follow, so we can find a fix for it. So far we haven’t been able to do this. For a quick fix, would you mind taking a full backup of your instance, reinstalling your instance following the standard install and restoring the full backup? That always seems to resolve the issue. We will keep looking at this though.

Several users were able to fix this issue, but it seems there is an array of possible causes.

I couldn’t do more than suggest a restore on a fresh, standard install without any custom settings, plugins, themes, or theme components.
