The issue occurred when the site was updated to PHP 8.3. It obviously has stricter rules. So after some changes were made to .htaccess, the login now functions fine. It is only the Google Login that strips the ?=ref..... from the URL.
I get it—yes, a higher PHP version means better security... but the admins should have taken that into account before switching to a different version; it would have prevented these issues. I'm glad it's working for you again; UNA is great, you just need to know what to set up, where, and how :)
