error while opening CHM after compiling help using doxygen - doxygen

Question

I am recently getting the following error while opening CHM file generated by Doxywizard version 1.8.16.
On a Win 7 m/c, I get the following error on all pages:
'$' is undefined
for every page.
it comes from the following line in index.html
$(function() {
initMenu('',false,false,'search.php','Search');
});
UPDATED LATER:
On a Win 10 m/c, i didn't get the above error, but a different error in some pages in the CHM as follows :
Unable to get property 'style' of undefined or null reference
This error happens within the jquery.js file.
