There are no errors that I can see - just nothing happens when you click on Next Step. Any ideas on how to debug? I only have one custom field - a radio box. I'm using 2.5.9 and J1.5.15.
Do you have the latest build of 2.5.9?? I would suggest downloading it again, reinstalling (or just manually updating files), then see if the issue remains. A few various issues have been worked out in 2.5.9 and you may be experiencing one that already has. If updating everything doesn't help, then submit a support ticket so we can check it out further.
i figured it out - I had dtregister as a public child menu item of an Admin menu item. That will cause the page to do nothing when you click Next Step.
