    Please go back and fix the problem(s)"

    You are much right, I was able to replicate the problem in your form, I uploaded a very small file (17.1 kb) and it won't submit.

    I noticed you have enabled FTP integration on your form. I'm suspecting you have the wrong authentication details or your FTP server's authentication details may have changed. Can you please reintegrate the form again via the submissions page by clicking settings (gear icon) on the upper right of the submissions, then > Send Uploads to FTP
