Hi Carlos,
Thanks for reaching out to us. Please confirm if your theme has any gallery options.
Our plugin will work with the default WooCommerce gallery. So, please try to disable the theme gallery option (if you have any).
Sometimes, the theme dev team changes some default behavior of the gallery. You can contact your theme dev team to enable the default WooCommerce gallery.
Thank You
Incompatibility with Besa theme
Carlos Gonzalez
Hello, we have the Besa theme installed for a multivendor e-commerce, together with this we have your Additional Variation Image Gallery plugin installed, which up to version 1.2.1 has worked correctly, but when updating this plugin it presents a conflict with the modals of the site, we would like to know if you have any solution from any other previous ticket for this problem or if it is the case to notify you,
Thanks
