region already defined Error Template Library Version 1.4.1

Are you sure these two lines trigger the error?

This message is generated by add_region(), which is either called manually, or from set_regions(). set_regions() is called from the init method, using the config file as input. At that time, the regions are defined. As it uses an array, 'header' can not be present twice.

So the question is, what code is in your controller?
