# How do I clear my Faaaster site's cache?

The **Clear cache** button, in the banner at the top of the site screen, purges the server cache — and the edge cache too if the CDN proxy is active on your domain. Use it when a change doesn't show up on the site even though it is saved in WordPress.

> **The server cache** stores generated pages so visitors can be served without calling PHP on every request. That's what makes the site fast — and what can delay a change from showing up.

## Clearing the cache

1. Open the site from your **Projects**.
2. In the banner at the top, click **Clear cache**.

The **Clear cache** button, at the top of the **Performance** tab next to **Restart**, does the same purge.

Every role can clear the cache, including **Viewer**.

## When should you do it?

- After a content or theme change that doesn't show up online.
- After installing or updating a plugin that affects how the site looks.

## Turning off the cache

The **Performance** tab, **Cache** section, **Server cache** row, shows the active cache type — for example **FastCGI Cache** — with the note "Changed via the server environment (Configuration)". However, the **Server** tab (whose page is titled "Configuration") offers no setting to turn this cache off: turning it off goes through a site configuration file.

1. Open the site, **Access** tab, **File Editor** section, then the `conf` folder (at the root, next to the `www` folder).
2. Open the `cache.user.conf` file, or create it if it doesn't exist.
3. Add the line `~^/ 1;`: it excludes every address on the site from the cache.
4. In the **Actions** menu, click **Restart PHP / Nginx**.

To turn the cache back on, delete this line and restart the same way. The same file also lets you exclude only certain pages.
