The error means that some layer (probably DNN) already added a handler named LogoffHandler*...For that you may contact DNN support...However if you want to replace the original handler with yours you can use the remove command...(order is important!)

XML

<remove name="LogoffHandler*" />
<add name="LogoffHandler*" ...="" />
