Updated WordPress and Drop Down Menu Stopped working

What theme are you using? Where did you download it from? Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the default theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

using dynamic wp theme from theme forest. found another thread that says its a query issue with updating wordpress and need to update to this:

if (!is_admin()) {
wp_enqueue_script(‘jquery’);
}

function init_dynscripts() {
    if (!is_admin()) {

		if ( function_exists('bp_is_blog_page')) {
			if (!bp_is_blog_page()) {
				wp_enqueue_script( 'bp-js', BP_PLUGIN_URL . '/bp-themes/bp-default/_inc/global.js', array( 'jquery' ) );
			}

		wp_register_style('dynamix-style', get_bloginfo('stylesheet_url'),false,null);
        wp_enqueue_style('dynamix-style');

somewhere in there need to be updated?

if (!is_admin()) {
wp_enqueue_script(‘jquery’);
}

You do not need to enqueue jQuery. It is loaded by default in WordPress. I’m sorry but as you appear to be using a commercial theme, you need to seek support from the theme’s developer/vendor. We do not support commercial products here.
