Easy Gallery used to work, but now it doesn't at all

Can I see a URL to a gallery that isn’t working on your site? Edit: nevermind got it

Sure
https://www.duofitgym.com/galeria-de-fotos/
https://www.duofitgym.com/musculacion/
https://www.duofitgym.com/body-vive/

Any of these used to work, the first link is the one with more images to show.

The Javascript call looks like it’s missing. It should be embedded at the bottom of the page. Do you pages still call the footer template and does your footer template have wp_footer() in it still?

Yes and yes, I think the only problem in the footer file is this line of code that is interfering the creation of the javascript call:

query_posts(array(
            'showposts' => 4,
            'orderby' => 'rand',
            'category__in' => array(get_cat_ID('Gym Motivation'))
        ));

I tried removing this line and it worked, added it again and it doesn’t, I use this code to show the images after the gallery plugin in the footer, does it affect the plugin in any way?

Are you saying that if you remove it, the gallery images pop up fine? If so, then yes it’s interfering ??

You should never use query_posts. Use wp_query() instead.

lol ?? obviously my bad, thanks a lot for your help!!
I changed my query_posts to this piece of code:

$args = array(
            'category_name'       => 'Gym Motivation',
            'posts_per_page'        => 4,
            'orderby'               => 'rand'
        );
        $the_query = new WP_Query($args);

and still didn’t worked, but then searching a little bit more, I identified the problem and it was that I missed the wp_reset_query(); call after the loop, so it doesn’t interfere with the plugin, which also uses a WP_Query according to what I understood.

Found the other solution in this site just for the record.

Well, thank you so much for your help! it was really appreciated, and sorry for the noob question ??

Ahh yes, every query should be reset or you’ll run into all sorts of issues ?? Glad it’s working now!
