In your case I think it might be due to your having two versions of jquery loaded -

/includes/templates/responsive_classic/jscript/jscript_a_jquery.js
/includes/templates/responsive_classic/jscript/jscript_jquery-1.12.4.min.js

I stand to be corrected but I don't think you should be loading both of these.
Looking at it again the jscript_a_jquery.js seems to be a customised version of jquery so that may be needed, but I forgot to mention the Google loaded jquery version of /ajax/libs/jquery/3.4.1/jquery.min.js, so it does seem that you have v3.4.1 and v1.12.4 loaded at the same time.

Getting a bit beyond my pay grade so hopefully someone can confirm this.
