I have build a Blog. Now I've tried to add the commenting function with "Comments": https://github.com/engram-design/Comments

I use the absolute basic template: https://github.com/engram-design/Comments/blob/master/examples/standard/standard.html

The call in my Tpl:

{% set params = {
   order: 'dateCreated asc'
} %}
                
{{ craft.comments.form(entry.id) }}

Until here everything is fine. When I want so send the comment, i always get this Error:

Property "Craft \ EntryModel.owner is undefined.

I know this is a noobie Question, but how can I fix this?
