MinimServer fails to start: 'Incorrect tag name' new error

Thanks for this. It looks like you have both a Composer tag (Ludwig van Beethoven) and a ComposerSort tag (Beethoven, Ludwig van). If so, your settings look fine but it would be a good idea to remove the duplication in this line:

tagFormat = Title.displayFormat={$composer$title^^^: },Title.displayFormat={$composer$title^^^: }
