CiviCRM Community Forums (archive)

We are using CiviCRM 3.4.5. When I log in as an admin, I can register for an event and get email confirmation. However, when I log out and test it as an anonymous user, I fill out the registration form and click Continue, I get a blank screen. Strangely, the data is successfully recorded when I check the registered participants.

I have CiviCRM, CiviCRM_rules enabled. For anonymous users, I have the following permissions enabled:

1. access all custom data;
2. access uploaded files;
3. profile create;
4. profile view;
5. view all activities;
6. reigster for events;
7. view event info.

What is missing here? We are stuck on this issue now and please help!!
