It is impossible to save changes to a custom content type that I have made. I have set the Preview before submitting to Required.
It is possible to make new content of this custom type, but every time I try to edit this content, the content is not saved. After pressing Preview and then the Back to editing and then Save, the article is not saved. The content is still editing mode.
When I go to Reports - Recent log messages, I find no relevant error messages.
This must be a bug, right?
