activeadmin: ActionView::Template::Error (arguments passed to url_for can't be handled.)

So, I’m UN-able to load any page in the admin navigation (e.g - /admin/users, /admin/comments etc…) on my Rails 4 app and get an exception/“we’re sorry something went wrong” error page when trying. Bare in mind that this error only occurs in production mode. Everything is working just fine in dev mode which makes it difficult for me to reproduce the issue in a new rails app and share it, unfortunately.

See the logs below, I’m sure that it has to do with the “arguements passed to_url can’t be handled” line just not quite sure the fix yet. Additionally, I’ve looked through similar cases all of which didn’t have a solution - so whoever can solve this is a gem!!!
