Thumbnail images opening in new page iso Thickbox

I’ve just checked the problem and it seems that the plugin is working correctly with the standard theme. What could be causing the problem with my custom theme?

Does anyone know what could be causing the problem?

What shortcuts do you use?

By the way, your link doesn’t work

Im using the [nggallery id=”1″] shortcode.

The link is https://tinyurl.com/apxfgn2 . I have check the plugin with the basic theme and it works there. Something must be wrong with my theme. I’ve added <?php wp_footer(); ?> and still the problem stays.
