My donation records are not being saved in the backend.
I searched the forum and got these suggestions, they were already implemented:
1) IPN must be enabled in the paypal account
2) Auto-return must be OFF in the paypal account
3) Permissions for /components/com_dtregister must be 755 and files inside 644. Also directories above /com_dtregister must also be 755.
I have DT Register operating on the same site with no problems at all.
I'm sure there's something very basic I'm missing...
