Learn Bash by Building a Boilerplate

I was working my through the tasks, when asked to move an image from one folder back to the website folder. But I kept getting an error, then it would not respond. So I refreshed the page, that didn’t help. I closed coderoad and opened it back up. I can see the directories that I created but I can not get it restart to track my progress. Is there something I can do to get this restarted without having to start from the beginning? Thanks in advance for any help or suggestions.
