jQuery.fn.load() is deprecated

@drwinn7

The fix is incredibly easy:

In wp-content/plugins/easy-accordion-free/public/assets/js/script.js, line 47, look for:

$(window).load(function () {

Replace it with:

$(window).on( 'load', function () {

I’m referring to the free version, but the pro version must have another instance. Try searching for it. If it is the same, do the same.

In wp-content/plugins/meks-flexible-shortcodes/js/main.js, line 42, the same:

$(window).load(function(){

Again, replace with:

$(window).on( 'load', function(){
