SiteOrigin Editor Problem

Hi,

I am currently using the SiteOrigin Editor and I have a problem if it. I am trying to add texts and images using this widget and when I click the “Done” Button and update the page, everything that I put in disappears in the editor and nothing is showing. I am only having a problem with the Editor, rest widgets from SiteOrigin are working. Can anyone please help, thanks
