Error Reporer in 2.1 says invalid email address

After update to 2.1 I do get this error message when I run it from site.
Thank you for reporting. Here is a fix:
Hi thanks for fast reply, I did the changes but now I get a blank window. And date of last log do not exist when I go in to the module.
Picture is from old shop(not 2.1) to explain what's missing.
You are right. This is a new behavior. LiteCart assumes the job was skipped if there was no output. I will be back with some output for the module. :)
Did you get the email before it emptied the log log file?
This will always produce a result for the log.
