Troubleshooting

No images found — Check the folder path under images/ and that files are JPG/PNG/WebP.
Shortcode not rendering — Enable the content plugin; use curly braces {photogallery …}; clear Joomla cache.
Lightbox not opening — Confirm assets load (disable conflicting scripts); hard-refresh the browser.
Filters missing — Need at least two categories from Name__file.jpg prefixes, and filter="1".
Editor button missing — Enable the editors-xtd plugin and reopen the article editor.
