This works 100%. The key was to add 'array('jquery'));' to js files in the directory instead of 'array(), '1.1.0', true );'

function theme_enqueue_scripts() {
 wp_enqueue_style( 'Font_Awesome', 'https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css' );
 wp_enqueue_style( 'Bootstrap_css', get_template_directory_uri() . '/css/bootstrap.min.css' );
 wp_enqueue_style( 'MDB', get_template_directory_uri() . '/css/mdb.min.css' );
 wp_enqueue_style( 'Style', get_template_directory_uri() . '/style.css' );
 wp_enqueue_script( 'jQuery', get_template_directory_uri() . '/js/jquery-3.2.1.min.js', array(), '3.2.1', true );
 wp_enqueue_script( 'Tether', get_template_directory_uri() . '/js/tether.min.js',array('jquery'));
 wp_enqueue_script( 'Popper', get_template_directory_uri() . '/js/popper.min.js', array('jquery'));
 wp_enqueue_script( 'Bootstrap', get_template_directory_uri() . '/js/bootstrap.min.js', array('jquery'));
 wp_enqueue_script( 'MDB', get_template_directory_uri() . '/js/mdb.js', array('jquery'));
 wp_enqueue_script('CustomJS', get_template_directory_uri() . '/js/custom-js.js', array('jquery'));
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_scripts' );

Hey Andre! Thank youuuu!!! It's working now!!! Thank yoou so much!!!

---

Suellyn Please can you check if solution provided by teawebsite is working for you ?? It looks like there is some issue with scripts linking. If this won't resolve your problem please contact me on m.szuchta@mdbootstrap.com.

Hi! Please can you check if you have the following line in your footer.php file. <?php wp_footer(); ?>

---

This is what is working for me: 1- first of all you have to work always with child theme: if you do something wrong or update core theme you don't lose your work. 2- in child theme create a folder (e.g: assets). 3- in assets put all mdb pro files. 4- because WP has its own copy of jquery first deregister jquery and then register your preferred version. 5- in functions.php link all css and js using get_stylesheet_directory_uri() because you are working with child theme. /******* DEREGISTER / REGISTER JQUERY *******/ function my_init() { if (!is_admin()) { wp_deregister_script('jquery'); wp_register_script('jquery', get_stylesheet_directory_uri() . '/assets/js/jquery-3.1.1.min.js', FALSE, '3.1.1', FALSE); wp_enqueue_script('jquery'); } } add_action('init', 'my_init'); /******* ENQUEUE CSS / JS *******/ add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' ); function theme_enqueue_styles() { wp_enqueue_style( 'Font_Awesome', 'https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css' ); wp_enqueue_style( 'Bootstrap_css', get_stylesheet_directory_uri() . '/assets/css/bootstrap.css' ); wp_enqueue_style( 'MDB', get_stylesheet_directory_uri() . '/assets/css/mdb.min.css' ); wp_enqueue_style( 'Style', get_stylesheet_directory_uri() . '/style.css' ); // your own style wp_enqueue_script( 'Tether', get_stylesheet_directory_uri() . '/assets/js/tether.min.js', array(), '1.0.0', true ); wp_enqueue_script( 'Bootstrap', get_stylesheet_directory_uri() . '/assets/js/bootstrap.min.js', array(), '1.0.0', true ); wp_enqueue_script( 'MDB', get_stylesheet_directory_uri() . '/assets/js/mdb.min.js', array(), '1.0.0', true ); } 6- Bonus trick : add this in functions.php to avoid WP adding <p> tag in blank space (lightbox not works without those functions) remove_filter( 'the_content', 'wpautop' ); remove_filter( 'the_excerpt', 'wpautop' ); Note: all MDB PRO 4.3.2 styles and functions I've tried are working except parallax css Hope this helps.

Hey Maciej! I put this line in my functions.php file, but I don't have this file and folder (inc/theme-setup/theme-enqueue-scripts.php).

---

Why should I have this file 'theme-enqueue-scripts.php' ? It didn't work too :/

---

Hey Please can you check if you have the following line in your functions.php file. require_once('inc/theme-setup/theme-enqueue-scripts.php');

---

Hello Maciej! How are you? Thank for your answer, but I tried to clear web browser cash memory and refresh it (Google chrome ctrl + F5 ) and use code with false, but not working yet. :( Js is not being called also when I use F12 (Network) to inspect.

---

I've changed the lines, however it continues not working :/ Sad but true. (º<º)

Hello Suellyn Your function looks correct so in this case first solution that might help is to clear web browser cash memory and refresh it (Google chrome ctrl + F5 ). Another solution that might work would be to change versions of attached scripts to boolean value 'false'. So function would look like this:

<?php

/**
* Include CSS files
*/
function theme_enqueue_scripts() {
wp_enqueue_style( ‘Font_Awesome’, ‘https://maxcdn.bootstrapcdn.com/font-awesome/4.6.3/css/font-awesome.min.css’ );
wp_enqueue_style( ‘Bootstrap_css’, get_template_directory_uri() . ‘/css/bootstrap.min.css’ );
wp_enqueue_style( ‘MDB’, get_template_directory_uri() . ‘/css/mdb.min.css’ );
wp_enqueue_style( ‘Style’, get_template_directory_uri() . ‘/style.css’ );
wp_enqueue_script( ‘jQuery’, get_template_directory_uri() . ‘/js/jquery-2.2.3.min.js’, array(), false, true );
wp_enqueue_script( ‘Tether’, get_template_directory_uri() . ‘/js/tether.min.js’, array(), false, true );
wp_enqueue_script( ‘Bootstrap’, get_template_directory_uri() . ‘/js/bootstrap.min.js’, array(), false, true );
wp_enqueue_script( ‘MDB’, get_template_directory_uri() . ‘/js/mdb.min.js’, array(), false, true );

}
add_action( ‘wp_enqueue_scripts’, ‘theme_enqueue_scripts’ );

?>

Hope that it will help.

Hi Suellyn, I had faced the same problem when I was developing a theme for WordPress, unfortunately I didn't found a solution to the problem yet :(
