Trouble uploading to CodeCanyon

Upon completing the form I click on the Upload button and the Processing… shows over the button but nothing happens… well after 15 minutes i get this message:

Which is strange cuz the uploaded files are less than 2MB in total…

I’ve tried again but the same thing happens. I’ve also tried to upload from another pc but same thing there.
UPDATE: Also tried to submit an empty form to see if the error notice that is usually there shows up, but it’s all the same.

Anyone else having this issue or it’s just me?
