My site has been been doing that ever since the first 2.7 release. It still hasn't been fixed in this 8th? revision of 2.7. They payment won't go through to the database even if you select pay at door. I have had an open ticket on it for several weeks now.
Did everything work on the older 2.6.9 version? I'm thinking I might need to use that version to get everything working. Need to get this registration up and running.
I had over 80 events that worked fine in 2.6, upgraded to 2.7 and everything broke.
I then dumped all all the old tables and did a clean install. It's never worked since and I can't get help with my support ticket. I have since abandoned using it in favor of using Webconnex which we used this last year. I was just hoping to go back to DT and get away the extra fees. It's not worth it to me to loose my clients over this. I have no other choice. We can just adjust out processing fee to makeup the difference and know that it works correctly.
I never downgraded. I didn't think I should have to downgrade something to make it work. Especially since it was a new installation and there would really be nothing to downgrade to. I'm beyond frustrated and gave up. Sad because alot of the reasons we switched last year from DT were addressed with added functionality in 2.7. It just doesn't work.
