I recently installed the module SiteSlugAsSubdomain on Omeka S, but I cannot validate the hostname. I keep getting a CSRF: Value is required and cannot be empty error.
The hostname is correctly configured and points to the server where Omeka S is installed.
Just a note on the Omeka module and plugin directory process… The Omeka Team doesn’t have a process for checking if third-party modules are functional. (We’ve got our hands full maintaining the core and our own add-ons.) Thus, if add-on developers are no longer maintaining their work it would be great if they asked us to remove them from the list. I’m not at all suggesting that this is the case with this modules, but the best way to make direct contact with the developer is through the github repository for the add-on with an issue.
Hello!! I was able to solve this issue after I took a close look at the code in the package I downloaded from the Omeka S modules page and compared it to the code on the GitHub page. It looks like the person who maintains the code updated the form elements to use Laminas in order to fix an issue (probably this one) with the configuration page in Omeka S v3. However, this fix was never uploaded to the Omeka S distribution page so you can only get the working version on GitHub.
I uninstalled the old version of SiteSlugAsSubdomain, and deleted the old files. Then, I downloaded the master code as a zip file from GitHub, unpacked that in my /modules directory, and renamed the folder to SiteSlogAsSubdomain. After that, I installed from the GitHub version. Configuration worked perfectly!
I have not tested the site navigation yet because we’re still building our instance, but this much worked so far. I hope that helps!
