I'm currently running DTRegister 2.4.3 on Joomla 1.5.10 Legacy Mode. When people sign up for our events using a credit card, the payment processes successfully and I can review the transaction on Authorize.net. However, when I look at the registration records in the admin panel, the PAID field is blank and the Payment type is also empty. Do you have any ideas on where the problem may be? I did perform an upgrade on DTRegister from 2.4.0 to 2.4.3. Could it be a problem with the database?
