My progress gets deleted and no way to claim the certificate

Hello. I completed all 5 of the Back End Development and APIs Projects. It says everything is alright, but once the page reloads, the progress is gone. I cannot navigate to the setting page without all of it getting reset. I spent so many hours on it and I do not understand why it keeps doing this. Can anyone help me?

when you submit a project, are you clicking on the button of the modal?

that is not a valid source code link

That could be the problem. I’ll upload my solutions to Github and get back to you.

You were correct. Now that my solution is on Github, I can claim my certificate. Thank you.
