We are rebuilding the live site with the new Porto version. On the dev site, the new gallery code does not seem to be able to open all images in the lightbox with the left and right scroll buttons as in the old gallery here;

When you click an image in the live gallery it opens in lightbox and then you have arrows left and right to scroll through all the images.
As with the old version we used the Default Galley code(elements-image-gallery.html) to build the new gallery but when you click an image only the one image opens in the lightbox, with no arrows to scroll to the rest.
Here is the code for the new gallery page with version 9.9.2;
OK, Wordfence is blocking the submission with the page code. I have included a link to the dev page in the Private Data box
