Unable to submit form

It appears that there are 2 submission dates for entries.

Main page with four steps: 19th November.

On the submission form with the criteria : 24th November

I have tried to submit a group's entry at 7:20 GMT but it does not allow me to do so: this form is currently not accepting responses

Can anyone shed some light?

Thank you,
