If the user clicks on a button marked in red (or orange), a dialog appears that lists the validation errors and warnings in the content in detail, with field names and error descriptions. The content cannot be saved or published until all errors displayed in the content fields have been corrected by the editor.
If there are only warnings, the content can still be saved, but it is recommended that the fields with warnings are also corrected.
In the case of multilingual content, the language in which the error or warning exists is also displayed in the dialog.
