Quark shows empty module 'gallery'

I am using the quark themes with no modification that I am aware of
I have created a Modular page (modular.md) with 3 modules pages using the gallery page template (pages are called gallery.md)
Each of the 3 module pages have some text and pictures
The module pages appear in the modular page nav but nothing gets displayed
I have tried changing the module page default from gallery.md to text.md to no avail

Here is the page vanbectarte.org/adventures

And the folder structure

06_adventures
modular.md
_fidji-nz
    gallery.md
    picture-1.jpeg
    picture-2.jpeg
_moroccan-christmas
    gallery.md
    picture-1.jpeg
    picture-2.jpeg
_norcal-bdr
    gallery.md

Thanks for your help

Quark doesn’t have adventures page type. It has to extend modular template. Check your plugins maybe, because this adventures most likely is not modular and comes from somewhere else

Thanks for the prompt reply and for catching this. I typed too fast, the file in the 06_adventures folder is called modular.md
I corrected my folder info in my previous message

@regis, See this post How to use the Gallery module in the Quark theme - #4 by pamtbaau

The template ‘gallery’ only works in concert with the premium Lightbox Gallery plugin.

@pamtbaau Thank you, I will check it out. I am also looking into the Unitegallery plugin. I will experiment with both and will report back.
In the meanwhile I was able to get the page to work by using the “text” template instead of the “gallery” template for my modules

Should be easy to add a module template to your theme for this plugin

Demo here

And it’s vanilla JS (no jQuery required), but to be fair, it’s still based on v4 of Photoswipe
