Smart slider – has stopped displaying photos

Hi @youmound

The problem on your site is a JavaScript error:
Uncaught TypeError: Cannot set property 'easeInQuad' of undefined
which you can check like this:

It happens because your site uses the Slim version of jQuery, but Smart Slider 3 can only work with the “non-slim” versions:

So I would recommend replacing the slim jQuery with the non-slim version:
<script src="https://yoursite.eu/wp-content/themes/sptrzyglow/js/jquery-3.3.1.slim.min.js"></script>
that should solve the problem.

File footer.php

<script src="<?php bloginfo('template_url'); ?>/js/jquery-3.3.1.slim.min.js"></script>

I have such an entry, it’s as if the template uses this file no? It finally worked, and on Friday it stopped .. (02/26)

You should replace the jquery-3.3.1.slim.min.js file with the non-slim version of jQuery.

Smart Slider 3 has never worked with the Slim version of jQuery, because jQuery slim removes some essential jQuery features, such as the jQuery Easing what is required for Smart Slider 3 to work:

If you didn’t have problem before, then probably something loaded a non-slim version of jQuery previously, before this slim version was loaded, so your site was actually using a regular jQuery version, what works well with Smart Slider.

I don’t think I understood you. Should I remove the slim version or add me?

Remove the slim version from your theme, and replace it with the non-slim version of jQuery.

So at the end your theme doesn’t load jquery-3.3.1.slim.min.js but jquery-3.3.1.min.js

Ok,

I add: <script src="<?php bloginfo('template_url'); ?>/js/jquery-3.5.1.min.js"></script>

and all work :), thanks
