Overview

A bug has been confirmed in versions 3.6.19 and 3.6.20 of the Omeka S IIIF Server module where URIs are malformed.

Specifically, the FQDN becomes incorrect, like the following.

Workaround

As of the time of writing this article, version 3.6.21 has not been released, so I recommend using version 3.6.18 or earlier of the module.

Summary

I hope this serves as a useful reference.
