Hi Omar! I hope you are doing well.
“Several students are reporting this bug simultaneously, so maybe there is something going wrong on one of the AWS clusters running Coursera.”
Our mentor Paul “asked the course staff for help. The mentors can’t see the backend infrastructure, but hopefully the course staff can either see what is going on or know someone to call at Coursera.”
Kindly wait and someone will get back to you.
Best,
Saif.

Thank you so much. I’ll wait 
Hi everyone! Sorry for the delay.
Kindly try this:
- From the blank notebook, click
File -> Open. - Tick the running notebook.
- Click
ShutdownthenDuplicate. - Rename the old notebook (any filename).
- Rename the duplicate with the original filename (basically, just remove the
-Copy1string). - Open this newly renamed notebook.
- You should be able to save this and also see the submit button after a minute.
You “might see an error about checkpoints failing. I think that’s okay because that’s related to the permissions of the hidden .ipynb_checkpoints folder. That is not needed for grading as far as I know. The changes should persist in the actual notebook itself even if they see that error. I submitted the notebook and got the expected grade.”
Best,
Saif.
Hi Saif,
I tried to use your solution but encountered another warning saying that I do not have permission while duplicating the file.
Do you mind have a look at this problem?

Hi @Cat_X @Omar_Allam,
Try this temporary hack. It worked for many learners but didn’t work for a few.
Best,
