I having this error showing console.

Answer 1

I had the same issue and had to escape quotes like this:
Original code with error.

var activeLink = location.pathname  
$('a[href='+activeLink+']').closest('li').addClass('active'); 

Introduced escaping double quotes

var activeLink = location.pathname  
$('a[href=\"'+activeLink+'\"]').closest('li').addClass('active'); 

Answer 2

Although the other answer technically is correct (the syntax used in the selector isn't allowed anymore), the solution isn't to update jquery.js. The selector that is mentioned in the error is used by the Divi theme and the update of Wordpress (that also updated jquery and/or jquery-migrate.js) now disallows it.

The solution is to update your Divi theme. At this moment 2.7.5 is the most recent version. I just updated the theme on my Wordpress site and the problem is gone.
