I am not looking to fix the problem. The theme catastrophically breaks the site. In Safari it just presents a blank screen, In Chrome an HHTP error 500 is reported.
Some plugins that have not been tested in the very latest version can be very unstable. Lesson learned.Moodle actually removed the plugin, butI reinstalled it.
As I said, this is mostly a heads up for those upgrading and using the theme. Don't use it.
