Common issues

URL variable returns a wrong URL

If your URL looks like this: and it leads you to either to the homepage or to a 404 page, the problem can be that your article is not accessible. Go Menus → select one of your menus, which is visible on the frontend → Add a new menu item to it → select Articles - Single Article and select the article, which suppose to be within the slider. Save it down and take a look, if you can access the article from your own menu. If you can't, make sure, that the article is published and also check out its category, if it is published and accessible for every user role.

Once the article is accessible, clear the slider cache and the url variable will be fine!
