Unexpected token <

Hi.

When I am on this page domain.com/lp-courses/ and click on a course, it does not open the course page and shows a jQuery error.

Uncaught SyntaxError: Unexpected token <
at eval (<anonymous>)
at jquery.js?ver=1.12.4:2
at Function.globalEval (jquery.js?ver=1.12.4:2)
at HTMLScriptElement.<anonymous> (ajax.min.js?ver=4.7.4:1)
at Function.each (jquery.js?ver=1.12.4:2)
at a.fn.init.each (jquery.js?ver=1.12.4:2)
at slideInNewPage (ajax.min.js?ver=4.7.4:1)
at j (ajax.min.js?ver=4.7.4:1)
at Object.success (ajax.min.js?ver=4.7.4:1)
at i (jquery.js?ver=1.12.4:2)

What is the problem?

Thank you
