It looks like you imported and old (pre JRS 6.0) theme into your JRS 6.0.1 instance, is that the case? You may have done this without knowing by importing a full repository from a backup.
If that is the case, I attached to this thread a clean JRS 6.0.1 theme. You may need to delete the one you have and upload this theme with the name "default", remember to upload this as a Theme not as a repo import.
