OWL Carousel / Sliders not showing up - common issues

If your OWL Carousel / Sliders are not showing up in the storefront, there are a few common configuration issues that may be causing the problem. Below are the most frequent scenarios and how to resolve them.

1. Banner not showing in Slider

The most common issue is setting an invalid visibility interval.

Each banner can have a Valid From and Valid To date. If this interval is invalid (for example, set in the past), the banner will not show up in your slider.

If you’re using only one banner with an invalid interval, the entire slider will not display.

✅ Fix:

If your banner should always be visible, set a Valid To date far in the future (e.g., 1/1/2030).

2. Carousel types not showing in Storefront

Different carousel types have specific requirements in order to display:

🔹 New and Sale Product Carousels

• Must be inserted into a page or block.
• Your catalog must contain products marked as New or Sale.
• If no products are marked, the carousel will not display.

• Must be inserted into a page or block.
• Requires existing orders in your store (best sellers are calculated from sales statistics).
