# Common Configuration Mistakes

## Missing Availability Settings

The most frequent cause of products not appearing is failing to set availabilities throughout the entire product hierarchy. This includes:

* **Meal level**: The main product must have availability set.
* **Product level**: Individual items within meals require their own availability settings.
* **Customisation level**: All customisations and add-ons need availability configurations.

When any level in this hierarchy lacks proper availability settings, the entire product chain becomes unavailable.

## Nested Meal Structure

Creating meals within meals causes system conflicts and prevents proper display.
