After wordpress update 5.8.3 does not working jquery [closed]

Solution 1:

Did you try installing the jQuery Migrate Helper Plugin: https://wordpress.org/plugins/enable-jquery-migrate-helper/ ?

This helps you to keep outdated jQuery-Versions working in your WordPress-enviornment in first place.

If I was facing problems like that, I would be thinking about re-building the calculator.

Solution 2:

Solved it, put those code rows into functions.php and jquery worked.

if (!is_admin()) add_action("wp_enqueue_scripts", "my_jquery_enqueue", 11);
function my_jquery_enqueue() {
   wp_deregister_script('jquery');
   wp_register_script('jquery', "http" . ($_SERVER['SERVER_PORT'] == 443 ? "s" : "") . "://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js", false, null);
   wp_enqueue_script('jquery');
}
