Troubleshooting

Confirm the module is published, in a real template position, and assigned to the menu item.
After changing parameters, clear Joomla cache if enabled, then hard-refresh (Ctrl+F5).
Category filters need a category on each slide (or article categories).
Deep links and Copy Link require URL Anchors ON.
Icons need Font Awesome on the site (most Helix/JoomlaX templates already load it). Use classes such as fa fa-info-circle.
No jQuery is required. Older docs mentioning jQuery apply only to versions before 2.7.
On mobile, swipe the tab strip horizontally if titles do not all fit.
