Affects Version/s: 2.0.4, 2.1.1
Fix Version/s: None
The problem is occurring for 2 reasons I think.
- Someone has a space in the username part of their email address
- Cron tries to email them and is considered invalid email address
The log entry fails to be added because url parameter is blank during cron processing.
Current case is email with username part of their email address.
Email assumingly forum trying to be sent to them via cron.
This is the error generated via the email_to_user function.
