Two jQuery/javascript errors after update to 3.5

This morning I have updated my site – http://www.marketingpolityczny.org – to v. 3.5. Instantly the browser console reported below errors with two javascripts based on jQuery. Thus the slider plugin on the mainpage stopped working as well as the top smooth scrolling script on every page. I tried to turn off the plugin and remove the script but no effect so far. Please help!

1. Uncaught TypeError: Cannot read property ‘0’ of undefined jquery.animate-colors-min.js:7
