Why are we geting notification that we are out of space?

Keeps telling me I don't have enough space. 

I only have 4 forms and 281 entries.  Should still be on a free plan.  

All my forms are blocked, please help.  

I have checked you account and noted that you have exceeded the allocate upload space as I had responded to you thread here: https://www.jotform.com/answers/1424251

Kindly do let us know if you need further assistance.
