It seems like that message is referring to the number of secure submissions you have received (7 out of 10) rather than the amount of space left in your account. Then again, I suppose it's possible that the notice is referring to space remaining in your JotForm Dropbox folder. Do you have almost 100 mb of files in that folder? If so, download them to your PC and delete them from the folder.
You are using SSL for your form, which means each submission made counts as a secure submission. Free accounts are limited to 10 secure submissions, 100 regular submissions, and 10 payments. Whenever you reach any of those limits, your forms will get disabled. They will only be re-enabled in the following month, after your limits refreshes. You may also upgrade your account to Premium or Professional, to enjoy higher submission limits and disk space.
The reason why you're getting a warning "You're almost out of space" is because your account currently has 7 secure submissions. When it reaches 10, your forms will be disabled.
To avoid using up your secure submissions, use regular http in your embedded form instead of https. Please do it as soon as possible, to avoid inconvenience on your part.
Hope this answers your question. Let us know if there's anything else.
