I confirm that I have the same problem on my side.
I'm not sure if it is related, but it looks like the time on your server is not particularly correct..
... the AUC awaits to be soared... :-/
Thank you for your notice - I'm very sorry for the late response. I'm currently travelling abroad.
I contacted the server administrator regarding this problem. It will be solved soon (hopefully).
Now it seems that you can submit, but your submissions are not evaluated (pending "0"...) ? :(
I still can't make submissions. BTW -- score 0 seems to be a temporary one, I had this situation several times and some time later proper score was displayed.
I have a situational update from the administrator of the server which hosts our platform.
The issue has been identified but to restore the normal behaviour of the system the machine needs to be switched off for a short period. This will be done during the night and you may experience some problems with access to the platform until the morning.
Thank you for your understanding. This time it turned out to be something independent from our system... :-/
