Hi everyone,
I installed a webwork server by following the instructions in WeBWorK 2.16 Ubuntu Server 20.04 LTS Amazon Machine Image.
Everything seems to work quite well except one thing.
When I click on the "Email Instructor" button to send an email, it fails and generates an error message if there is any Korean letter in the email.
It does send an email successfully if I use English letters only.
Has anyone experienced a similar situation?
Just in case I wrote the error message below.
Any suggestions would be appreciated!
Thanks in advance!
