Error : ' Element 'Views' is not valid for content model '

If you see following error message when starting presentation services, possible reason for error would be, you may have same tags twice or so.

In my case I have 2 time 'Views' tag in the instance config file. When I'm trying to start presentation services it has thrown following error. Just delete one of 'Views' tag then everything worked fine.

Element 'Views' is not valid for content model:
