Warning: 'headingmode=$1' has no effect with 'ordermethod' on a single component. Using: '$2'. Help: you can use not-$2 'headingmode' values with 'ordermethod' on multiple components. The first component is used for headings. E.g. 'ordermethod=category,comp' (comp is another component) for category headings.
