If you try to add wikitext - the stuff - in the visual editor, it gives that message. You've got two options:


 * Don't add wikitext when you're using Visual Editor. See Help:VisualEditor for the basic info on the editor.
 * Don't use the Visual Editor, but edit in Source Mode. This might be more troublesome to newer users, as the Editor's main goal is to accomodate people who aren't familiar with wikitext. To disable it, go to Special:WikiFeatures and switch the New Visual Editor off.
