Hi!

​

Thank you for the update.

​

In your installation, we noticed that the layerslider jquery script has this attribute, which does not exists in our own installation.

​

data-cfasync="false

​

This was added using a filter, so we used this snippet in the functions.php file to register the scripts again and remove the data attribute.

​

​

add_action("wp_enqueue_scripts", function() {

    wp_deregister_script('layerslider' );

    wp_deregister_script('layerslider-utils' );

    wp_register_script('layerslider', LS_ROOT_URL.'/static/layerslider/js/layerslider.kreaturamedia.jquery.js', array('jquery'), LS_PLUGIN_VERSION, true );

    wp_register_script('layerslider-utils', LS_ROOT_URL.'/static/layerslider/js/layerslider.utils.js', array('layerslider'), LS_PLUGIN_VERSION, true );

}, 999);

​

function avf_script_loader_tag_mod( $tag, $handle, $source ) {

    if ( "layerslider" === $handle || "layerslider-utils" === $handle ) {

        $tag = str_replace( "data-cfasync=\"false\"", '', $tag );

    }

​

    return $tag;

}

add_filter( 'script_loader_tag', 'avf_script_loader_tag_mod', 999, 3);

​

add_action("after_setup_theme", function() {

    remove_filter('script_loader_tag', 'layerslider_script_attributes', 10, 3);

}, 999);

​

The jQuery errors are now gone, but the old sliders are still working properly. However, newly created sliders work just fine. Please check the private field.

​

Cheers!
