Where can I find the debug logs of a visuarlforce email template?

I have a workflow rule that actions an email alert with a visualforce email template, but I cannot see the logs of the controller of the visualforce component used in the visualforce email template

Hey,

I was curious to hear about people's experiences of creating a new instance to migrate an existing org which requires a lot of changes.

An example of what I think is a major update is the fact that the organisation was not setup to use person accounts when their clients are actual private customers and not businesses.

I've been running some tests and it looks like the primary campaign source does not automatically populate for opportunities created on person accounts attached to campaigns. Has anyone else noticed this? Is there any way around it? I would like the opportunities to be associated with the most recent campaign attached to the person account.
