From the screenshot you are certainly over your current disk space usage.
However, we can see you may have also 'accidently' manually suspended the domain. I have removed this. Please allow up to 1 hour after this update for your local DNS / cache to reflect this change. This was done under domain setup > selecting domain > unsuspend domain.
We can see most of your usage is now in your .trash folder which seems to have been all of your WP content? You may want to use your file manager to restore those files. Once restored let me know and we can certainly increase disk space as needed.
