Hi @alexhike,
I believe the issue here is being caused by another plugin that is shortening your image URLs, specifically the URL’s set on FooGallery’s thumbs which point to the full size image. So the FooGallery thumbs’ href attribute is being converted from https://www.alexhike.ca/wp-content/uploads/2019/09/WEJB2245.jpg
to https://www.alexhike.ca/wejb2245/
.
FooBox can open multiple types of URLs such as videos, iframes, raw HTML and images however to be able to do so it inspects the URL of the item to determine how to open it. In this case you are using FooBox Free which only supports opening images. To determine if a URL is an image it inspects it and sees if it contains a filename and extension, specifically it checks for the following extensions: jpg|jpeg|png|gif|bmp|webp|svg.
If the URL does not pass this check then FooBox doesn’t know how to load it and so skips the item entirely. If there are no items found at all FooBox performs a cleanup of any used resources and then destroys itself. This is currently what is occurring in your page.
What is the name of the plugin you are using to shorten the URLs? Is it possible to exclude FooGallery items from being converted?
Thanks
Steve
