Page Builder Stopped Saving

I went back to Page Builder for the first time in a month and it seems that I can no longer save. If I upload a picture or type code or even plain text, it disappears when I update and preview or view the page. The only thing that I can save is to duplicate an existing widget and duplicate it. Nothing else saves. I have tried to turn off other plugins and even if Page Builder is my only active plugin, this problem persists. Please help.
