The error is likely in the theme. I use Themify Flow and in this thread https://themify.me/forum/topic/after-update-to-wordpress-4-5-theme-does-not-shown-as-it-was-before#post-198686 found the file and made the needed change.
Your theme may have the bit of code in another location. Looking at your console info it looks like the file and path are
/wp-content/themes/itheme2/themify/themify-builder/js/themify.scroll-highlight.js
Always make a backup first!!!!!!
On line 194 Edit the bit of code a[href*=#] to a[href*=”#”]:
$( this.options.context ).find( 'a[href*=#]' ).not( 'a[href=#]' ).on( 'click', function (e) {
to
$( this.options.context ).find( 'a[href*="#"]' ).not( 'a[href="#"]' ).on( 'click', function (e) {
