I am getting 'Technical Error' when submitting answers in Contest Validation Tutorials.
Is it something related to my user id?
The "Technical Error" alert is usually when there is a session error (time out is the most common). If you are logged in, refresh the page (so you have a valid, active session) and still get an error, please let us know and we can investigate.
Unfortunately, I am still getting the "Technical Error" when trying to submit an answer in a valid, active session.
