I have the same problem with Angus after updating to the latest WP version. It sucks a lot as the author was selling his theme with the promise of regular updates. It looks like the only right solution is to change my whole website to a different theme. I’m looking at new themes through themeforest, but what guarantee do I have that the authors of that theme will still be writing updates one year from now? Will I have to design a whole new website every time WP comes with an update?
