The error only happens in an attempt to save the page in a real-time editor via an in-line editor or WYSIWYG editor. I can save page without errors only in Wiki mode. Also, after a failed action, if I check the source code of the page from the CKEditor toolbar, I may accidentally save the page from the Wiki editor with parsed content.
