JonLebkowsky on "Javascript Errors"

I'm seeing console errors in both Chrome and Firefox at this site: http://cyw.academy

SCRIPT_DEBUG didn't fix the errors.

The errors:
1) ReferenceError: jQuery is not defined
at jquery-migrate.js:752:1

2) Syntax error, unrecognized expression: a[href*=#]:not([href=#]):not(.cf)
at jquery.js:2:12733

The errors are appearing in console - you can see on the home page.

I'm baffled - can't determine how to address the errors. I did try adding

define('CONCATENATE_SCRIPTS', false );

to wp-config to address the first issue, but it didn't resolve the error.
