Why does it say my forms are over quota

I changed the setting so that I would have unlimited views for our forms, however, it is now saying we are over quota. What made this happen? I changed that setting weeks ago and the forms have not come back. Is there anything else I can do?

I have been using these forms for years now and have never had this trouble. It has just been in the last 2 months.

Please help.

Here is one of the forms - https://form.jotform.com/21994217246155

You are much right, it shouldn't be suspended as you have unlimited form views due to enabling the Jotform logo at the footer of the forms.

I've unsuspended the forms. Let us know should the problem persists.
