Filled up a form and receive Form Over Quota error

I have failed to upload my job application documents on the link which was provided, I only see this notification "Form over quota"

Hi Mukiibi, 

Thanks for reaching out to Jotform Support. Do you mean you filled up a form, but you get a Form Over Quota error after submitting? Please be aware that Jotform is an online form builder and does not have direct involvement with the content or management of individual forms created by our users. It sounds like you might have filled out a form that is managed by a Jotform user. If that's the case, I recommend reaching out directly to the owner of the form for assistance with your issues. You can do this by replying to the confirmation email you received after submitting the form. This reply should go directly to the email address of the form's owner or the designated recipient.

Let us know if there’s anything else we can help you with.

Thank you for the feedback though the deadline has now passed, but I was
redirected to the link when applying for a job, as per the attached
screenshot only to get the Quora notification.
