# X_LOCAL_STORE_UNAVAILABLE

## Means

the page's durable store could not open

## Typical cause

IndexedDB is blocked or absent (a private window, storage disabled, a runtime with no `indexedDB`), so persisted records and queued writes live in memory and are lost on reload. **A warning, never thrown**: `console.warn` once, and the page carries on, because a page never breaks for being unable to remember. 21.0.0

## Fix

nothing to do in the app. Allow site storage in the browser (a private window blocks it) and reload
