The Gallery Slider Pro plugin is compatible with most of the popular WordPress page builders and themes like Divi, Elementor, etc. It automatically replaces the single-page product gallery section with the WooGallery Slider plugin. But in case you face any issues displaying the WooGallery Slider with any theme or page builder, you can use the WooGallery Slider shortcode from the WooGallery Slider > Advanced > Shortcode [wcgs_gallery_slider]. 

Just add the shortcode on the single product page where you want to show the product gallery to fix any display issues. If there’s any custom-built product gallery and you don’t want to use it, then remove that custom-built gallery and add the shortcode instead.
