# 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`).
