Why ar we getting Over Quota error?

Hallo, please help me

My form not show. I still have many quotas. Please help me to show my form.

thanks

I have tested accessing the account and I was not able to replicate the issue. I have however cleared your form cache just in case we have some cached data causing the error above.

Kindly try accessing the url and if you still experience the issue kindly try clearing your browser cache.
