Validation and upload

Hi, I’ve already posted a topic like this and I’ve thought the problem was solved.
Unfortunately the page:
https://www.campaniaturismo.org/admin/admin-foto-add-new.php
doesnt run I 'm going crezy.
This is a console screenshot.


I 've added server side validation (do not exist in database) and several client side validation roles.
Please can anybody help me.
What does the message from console mean?
Thank you
