TOPIC: Problems after 1.5 migration

I believe I followed the migration directions exactly, but I have two issues:
1) When I try to save a record for an existing event, I get an SQL error updating the xxx_dtregister_group_event table. The table on my system doesn't have several fields that are included in the update statement. The first missing field is 'event_admin_email_set'.

I'm guessing that the table structure didn't get updated when I installed DT Register. My old server is using DT Register 2.7.2a - could it be that the old system needs to be at a later version in order to have all the requisite fields?

Well, if you migrated directly from 2.7.2, you did NOT follow all of the instructions. You MUST upgrade the 1.5 site to the latest version of DT Register for 1.5 FIRST. Then you can export the data to migrate. Not doing that, you will have MANY missing database fields. You'll have to scrap any DT Register data on the 3.x site and go back to do it again.

OK - As far as I can tell from your site, 2.7 seemed like the most recent available for Joomla 1.5.

Is there a download area where I can get the update for our old 1.5 site?

The latest for Joomla 1.5 is DT Reg 2.7.25... and it's included in the current download package. The package has the latest build for Joomla 1.5, 2.5 and 3.x.
