Thanks. I filed a bug report on your web site. Here is an update for others reading this support thread.
I found and fixed one problem only to find another. A plugin was adding a “defer” parameter to the link for jquery. Since Envira adds inline script in the header right after all the queued scripts are loaded, jquery wasn’t ready for it yet. There was a “jQuery undefined” error because of this. It might be better to surround that code in an onDocumentLoaded event.
After the defer issue was fixed, the images now load on the gallery page as normal. When you click on an image in the gallery, it opens in a lightbox, so that works too. But there is no way to close the lightbox or navigate to the next image in the gallery. When I looked at the javascript debug console, I saw this error immediately after clicking an image to view it…
