My form still shows "overquota" on my webpage

It looks like my form hit the monthly limit on July 31st. When does that monthly limit reset? I was assuming it would reset the count on August 1st. It's now August 6th and my forms still aren't working. 

We are sorry for the inconvenience this may have caused. I cleared your form caches and that fixed the issue, kindly check your webpage and see if the issue persists on your end.
