# Fix common problems

Start with the message on screen; Chapbook keeps destructive recovery steps explicit.

Chapbook manual. Web page: https://chapbook.ink/manual/troubleshooting/

## I cannot sign in

Use **Email me a sign-in link**, reset the password, or resend email verification from the screen you reach. Check spam. Open a sign-in link on the same device; password-reset links expire after one hour. An invalid reset opens **Request a new link**.

## A source will not load

Check the supported type, file size, rights, and whether the URL is public, then try again. Open the **Couldn’t read** detail, remove the source, and add it again. Private and local URLs are not supported sources. See [Notes & research](/manual/notes-and-research/) for limits.

## Writing or export stopped

Read the job message, retry the action, and use **Stop** only when you intend to cancel the running work. Insufficient credits leads to Billing; an action that needs a paid plan asks you to choose one.

For a repeated export-tool or build failure, retry once, then contact support with the book title, action, time, and visible error code. Never send a feedback link.

## Preview is out of date

**Changed since this preview** means the book moved after the last render; choose re-render.

## The public page is not showing my edits

A live page is a snapshot; choose **Update page** to publish the current revision. The cover thumbnail follows the currently selected cover. A lapsed page stays at its last published version; updating needs a plan.

## A link no longer works

A stopped feedback link, unpublished page, changed handle, or changed slug invalidates the old address. Create or copy the current address from the relevant book page.

## A chapter changed elsewhere

Copy any unsaved text somewhere safe, reload the chapter, and reapply your change to the newest revision. See [Suggestions & revisions](/manual/suggestions-and-revisions/) for revision recovery.

## When to contact support

Write to [support@chapbook.ink](mailto:support@chapbook.ink) when retrying does not resolve a repeatable error, a page was taken down, or a trashed book needs recovery.
