It looks like something is using and I had blocked in the xdt transform because I was afraid it would allow someone to accidentally remove the redirection. Something recently changed, though, and I had to remove locking of attributes to make the extension start working again. Can you try upgrading to the latest version of this extension and see what happens now?
