WP_ENQUEUE ERRORS & FIXES

Hi Jahidul,

Good day

The error is cause by the enqueue script and style it should be wrap inside function and triggered by add_action. You will see the error when you enable the WP_DEBUG to TRUE.

See below code OLD

wp_enqueue_script('x-jquery-easing', X_PLUGIN_URL.'js/jquery.easing.min.js', array('jquery'));
wp_enqueue_script('x-jquery-main-scroll-up', X_PLUGIN_URL.'js/jquery.scrollUp.min.js', array('jquery'));
wp_enqueue_script('x-jquery-active', X_PLUGIN_URL.'js/active.js', array('jquery'));
wp_enqueue_style( 'wp-color-picker' );
wp_enqueue_script( 'my-script-handle', plugins_url('js/my-script.js', __FILE__ ), array( 'wp-color-picker' ), false, true );

wp_enqueue_style('x-scroll-plugin-css', X_PLUGIN_URL.'css/custom.css');
wp_enqueue_style('x-scroll-plugin-fontello-css', X_PLUGIN_URL.'css/fontello.css');

Change to NEW

function add_x_scroll_style() {
    if ($GLOBALS['pagenow'] != 'wp-login.php' && !is_admin()) {
        wp_enqueue_style('x-scroll-plugin-css', X_PLUGIN_URL.'css/custom.css');
        wp_enqueue_style('x-scroll-plugin-fontello-css', X_PLUGIN_URL.'css/fontello.css');
    }
}
add_action('wp_enqueue_scripts', 'add_x_scroll_style');

function add_x_scroll_script() {
    if ($GLOBALS['pagenow'] != 'wp-login.php' && !is_admin()) {
        wp_enqueue_script('x-jquery-easing', X_PLUGIN_URL.'js/jquery.easing.min.js', array('jquery'));
        wp_enqueue_script('x-jquery-main-scroll-up', X_PLUGIN_URL.'js/jquery.scrollUp.min.js', array('jquery'));
        wp_enqueue_script('x-jquery-active', X_PLUGIN_URL.'js/active.js', array('jquery'));

    }
}
add_action('wp_enqueue_scripts', 'add_x_scroll_script');

function add_admin_x_scroll_scripts() {

    //Register color picker script
    wp_enqueue_style( 'wp-color-picker' );

    wp_enqueue_script( 'my-script-handle', plugins_url('js/my-script.js', __FILE__ ), array( 'wp-color-picker' ), false, true );
}

add_action(‘admin_enqueue_scripts’, ‘add_admin_x_scroll_scripts’);
Hope this helps and if your satisfied with the code kindly update your plugin.
