## 説明

**WP Fix It Easy Security Headers** adds a simple page under **Tools  Security Headers**
where you can toggle common HTTP security headers:

 * **Strict-Transport-Security (HSTS)**
 * **Content-Security-Policy (CSP)**
 * **X-Frame-Options**
 * **X-Content-Type-Options**
 * **Referrer-Policy**
 * **Permissions-Policy**

On activation, all headers are **enabled by default** and you’re redirected to the
settings screen.

For convenience, the page and the Plugins screen include a **“Check Headers”** button
that opens SecurityHeaders.com with your site’s URL prefilled (built dynamically
from `home_url()`).

### Notes on CSP

This plugin ships with a **permissive** default CSP intended to “work everywhere”
out of the box (allows most external sources and inline code). For stronger protection,
you should harden the directives for your specific site.

### Key Features

 * One-click toggles for popular headers
 * Dynamic “Check Headers” scan link
 * Uses the WordPress Settings API (nonce + capability checks)
 * Output escaping and sanitization following PHPCS

## インストール

 1. Upload the plugin folder to `/wp-content/plugins/fix-it-easy-security-headers/`
    or install via Plugins  Add New.
 2. Activate the plugin.
 3. You’ll be redirected to **Tools  Security Headers**. Review and adjust toggles 
    as needed.
 4. (Optional) Click **Check Headers** to verify your headers on SecurityHeaders.com.

## FAQ

### Where do I manage the settings?

Go to **Tools  Security Headers**.

### What happens on activation?

All header options are enabled and you’re redirected once to the settings page.

### Will this break my site?

Most headers are safe defaults. The provided CSP is intentionally permissive; it
shouldn’t block assets. For strict CSPs, tailor directives to your stack and test.

### Can I use this on multisite?

Yes. The “Check Headers” URL is derived from `home_url()`. Activation redirect is
skipped for network/bulk activations.

### Why don’t I see a “Settings saved” notice twice?

The page prints only this plugin’s scoped settings messages to avoid duplicate notices.

### Can I customize the CSP?

Yes. You can modify the `$csp` string in `security_headers_add_headers()` to fit
your site’s needs.
