Email notifications work excellent when users are logged in. But in my setup I get an awful errorpage when not logged in. That's why I am looking into the notification set-up to work around this issue.
The homepagelink in that page defaults to http://www.verenigingzonn.nl/wp-admin/index.php and without any navigation from the website. This is probably due to my own lack of insight into the cause. So I need good advice to solve this please.
