when I create new users, the first invitation e-mail is sent correctly. Also the test mails from the configuration page within the global settings are going through fine.
But when I try to resend a mail for a user whose invitation link has expired, I only get the message "error:" in the status.
How can I go more into details to have a look at this behaviour?
I enabled debug (=1) in the config, but don't see any error messages in the Apache access or error log.
