I just installed new versions of DT Register and JEvents. AFter syncing everything, the events look good (thanks Nathan for your help!).
I entered a test registration and out of 17 custom fields, only 6 of them stored the data in my registration record. It appears as though i did not enter anything but i did. Most of these fields are required to register.
Same problem here, I think DTH is working on it as they visited my site as admin and would have seen the problem .. no news yet . For me it was the multi select check boxes. Data saves in DB and works in export but does not show in back end registrations records.
I actually had to to do a backup restore with previous versions of DTReg and JEvents, as the registration data was very messed up (whole classes of registered students gone). I have to clean up some event records, and then I will try the upgrades again! Hopefully, I will be a smoother transisition this time around.
If I remember correctly though, it was not just the checkbox fields that did not save. I had one that was a phone number, at least 2 that were text fields for comments, and a couple of check box fields that did not store the data.
