New install. Cannot figure out why this error is occurring.
This site is under development and cannot go live until this issue fixed.
Thought it might be because this is a sub site of another website.
Any ideas?
Please download DT Register again by logging in, going to My Orders. Reinstall with the latest package. If your issue remains, log a support ticket so we can check it out.
Looking at your site, I did not get a 404... just a redirect to your user login. The menu item associated with that url must be set to Registered access. When I accessed the DT Register component without that Itemid, the page loaded fine... outside of the popup saying the Google Maps API key is missing... but you just need to get that from Google and that will go away.
