Troubleshooting

Fixes for the most common Diapo Slideshow problems.

• Nothing appears

  • Check Published, Position, and Menu Assignment. Confirm at least one slide has an image. An empty source renders nothing on purpose.

• Images stack with no arrows or captions

  • The CSS or JS did not load. Confirm media/mod_diaposlideshow/css/diapo.min.css and js/diapo.min.js exist. Clear Joomla cache and hard-refresh.

• Folder source is empty

  • Pick a folder under images/ that contains JPEG, PNG, GIF, WebP, or AVIF files. Other file types are ignored.

• Article source is empty

  • The category needs published articles with intro images. Items without an intro image are skipped.

• Split looks crushed in a sidebar

  • Split stacks when the module is narrow. That uses a container query, not the window width. If it still looks crushed, hard-refresh so the stylesheet is current.

• Autoplay never starts

  • Autoplay is 0 (off) by default. Set a positive number such as 5000. Play / pause Auto only shows the button when autoplay is on.

• Language keys show as MOD_DIAPOSLIDESHOW_*

  • Reinstall the package so language files copy, then clear cache.

• Old look after a change

  • Save the module, clear Joomla cache, then Ctrl+F5.
