rankings are stuck

I have purchsed the stylish and the rankings and am attempting to run it on https://showcase.hickhopmusic.com My rankings initially worked, but now they’re stuck on the initial rankings and not showing up to date info. I have changed my theme, and deactivated all plugins. I am working on a multisite. Can you help me fix the rankings? It is one of the main features of this site. Thanks
