I want to set up a self-registration process for a community. When I submit the data from the registration form there occurs an error message:

Error occurred while loading a Visualforce page

It's not very helpful. So I got the idea to debug. But I didn't find out how to debug communities.

Can anybody help me please?

  • For that error it might just be permissions, but you can use the standard debug log from the developer console probably as guest user to capture a non-registered community user. – Dave Humm Nov 16 '16 at 11:16
  • Thank you, that works. Unfortunately the log is not very helpful. Here is the message: 14:35:13:000 CODE_UNIT_STARTED [EXTERNAL]|06658000003BRm1|VF: /apex/Exception – nwolny Nov 16 '16 at 13:46
  • What could the permission problem be exactly? – nwolny Nov 16 '16 at 13:47
  • Each profile can have the permission to use a visualforce page granted, you can check this either from the profile or the VF page security settings. – Dave Humm Nov 16 '16 at 14:37
  • Okay I checked that in the security settings. Could the problem has anything to do with the guest user? Normally when a community is created with the wizard automatically a guest user is generated. But I don't see the guest user in the system (under manage users). I installed the community with all communities -> new community and then I followed the steps from the wizard. – nwolny Nov 16 '16 at 15:06
