# Open the theme editor and find your way around

Open **Online Store → Theme Settings** to launch the theme editor for your live store pages. The left icon rail holds your tools, the top bar switches pages and devices, and **Save** and **Published** are two separate actions.

## Steps

1. In the sidebar, click **Online Store → Theme Settings** (or **Online Store → Themes** → **Customize** on your active theme).
2. Use the left icon rail (icons only, top to bottom):
3. In the top bar, open the page selector (**Select Page** / **All the Pages**) to switch between Home, Product, Checkout, Cart and your custom pages; `+` **Create New Page** adds one.
4. Use the device switcher to preview the phone, tablet or desktop frame (plus fullscreen). Undo and Redo sit next to it.
5. Above the canvas, switch between **Page**, **Header** and **Footer**. Header and Footer carry the badge **Shared across all the store** because they are reused on every page.
6. Click **Save** to store your changes. The **Published / Unpublished** toggle is separate: Save keeps your work, Published decides whether visitors see the page.

## Common problems

- **Save** reads "Nothing to save" → there are no unsaved changes on this page; edits are saved per page and per language, so check you are on the right one.
- A red **Missing required blocks** alert appears → a block that page needs (for example **Checkout Form** on the Checkout page) was removed; use the alert's shortcut to open the block list and add it back.
- **Preview** is greyed out → preview is disabled on the Upsell, Order Completed and Thank-you pages.
- Changes are saved but not visible on the store → check the page is set to **Published**.
