Don't worry - your galleries didn't go anywhere!
We often hear the question "Where did all of my galleries go?" or "My galleries disappeared!" which prompted us to write this FAQ.
By default, the galleries list page shows only active galleries. That way, you don't have to view dozens (or even hundreds) of older, expired galleries, every time you load that page.
When a gallery expires, it won't show on the gallery list page by default. It didn't disappear; it's just being filtered out of view.
