If you missed the submission deadline you can ask the hackathon manager to enable late submissions in order to allow you to submit your project.
Please note: enabling late submissions is at the discretion of the hackathon manager. Not every competition will allow late submissions. Make sure to submit early - you can update your submission until the deadline.
Hackathon managers: if you are trying to enable late submissions read this.
