You may want to check the following settings:
- Make sure the "Show for document types" property value is empty and the "Document types" property is set to appropriate document type, such as "cms.news" (without double quotes).
- Make sure the "Transformation" value is set.
- If you specified any "Path" property value, set it to /% and test if it helps. If so, you may need to adjust the property value.
- If you specified any "Site name" or "Culture code" value, try to clear the values.
- If you specified any "Maximum nesting level" value, try to set it to -1.
- If you specified any "WHERE condition" value, try to clear it.
- Make sure the "Check permissions" value is set to false or - if you want to check the permissions - make sure that the current user has appropriate permissions.
