Unable to preview form

When I attempt to preview my form I receive the following error message: "The form is in restore mode please try again later" Also, all of my options are not saving. Below I have attached a screenshot of what I am attempting to update, but my options will not save. I have also included the URL for the error message.

Hello Brenda67,
