Settings Overview

FlipBooks → Settings is where you set the defaults for every FlipBook on your site. Configure your branding once and every new FlipBook picks it up automatically — no need to repeat yourself per FlipBook. This article maps the seven tabs in Global Settings, what each one covers, and how the override system works.

How the override system works

Most fields on a per-FlipBook tab have a switch labeled Global / Custom (or Global / On / Off):

Global (default) — uses the value from this Settings page.
Custom — overrides for this FlipBook only.

Workflow:

Set everything globally to your defaults.
Leave per-FlipBook switches on Global.
Only flip to Custom when a specific FlipBook needs a different value.

This way you can change a global default later (e.g. swap Brand Color from blue to red), and every FlipBook follows automatically — no per-FlipBook edits needed.

Some advanced settings (Page Videos, Hotspots, WooCommerce gating) only exist per-FlipBook — they don't have global defaults.

Where settings are stored

Global Settings are saved in the WordPress options table under tncfb3d_settings. Per-FlipBook settings are saved in post meta on the FlipBook post.

Export / import preserves both — when you export a FlipBook, only that FlipBook's overrides come along. When you export the whole plugin (via the Toolkit), global settings and FlipBooks both come through.

Recommended setup workflow

For a new site:

Tab 1 — General: pick default language, deep linking on, mobile single page on.
Tab 2 — Display: set your brand chrome, brand color, logo. This is the biggest one-time setup.
Tab 3 — Toolbar: enable the buttons you want; hide anything irrelevant.
Tab 4 — Protection: enable as little as you actually need. Watermark on for paid content; copy prevention for confidential content.
Tab 5 — Integrations: add Google Analytics ID, set up at least one cloud TTS provider if you want Read Aloud.
Tab 6 — Accessibility: leave all defaults on.
Tab 7 — Advanced: skip until needed.

Then every new FlipBook inherits your defaults — you only need to upload content and publish.

Disabled fields look greyed out

When a per-FlipBook field is set to Global, it appears greyed out in the editor at 70% opacity. This is intentional — it signals "this is inherited from Global Settings; flip the switch to override."

Troubleshooting

Changes to global settings don't appear on existing FlipBooks.

Per-FlipBook overrides win over global. Check the FlipBook's tab — if a switch is set to Custom, it's not picking up the new global value.
Clear caches (page cache, CDN, server cache).
Reload in incognito to rule out browser cache.

The "Save" button is disabled.

Some fields validate on the client side. If a value is invalid (e.g. font size out of range, or an invalid color), the button stays disabled. Check field-level error messages.

Custom CSS doesn't apply.

Confirm the CSS is saved (the CodeMirror editor needs a manual save).
Check that the CSS selectors match the front-end DOM (use browser dev tools to inspect).
Some custom CSS is overridden by per-FlipBook Custom CSS — check both.
