## 外掛說明

Need to **rollback WordPress** after a problematic update? Want to **downgrade**
to a known-good release, or move to a specific core version for testing?

**Raju Core Version Switcher** gives you clear control over the WordPress core version
on your site—from a simple settings screen, with optional one-click install and 
a guided workflow.

#### Why site owners and developers use it

 * Recover quickly when a core update breaks themes, plugins, or layouts
 * Switch to an exact WordPress version for staging and compatibility checks
 * Lock the site to a stable release while you plan the next update
 * Avoid guesswork with package checks and a clear progress path

#### Key features

 * Set an exact target WordPress core version
 * Automatic and manual version package checks
 * One-click install of the target version from the settings page (when you have
   permission)
 * Progress feedback during download and install
 * Save settings without a full page reload
 * Guided 3-step progress so you always know what to do next
 * Status panel with download URL verification
 * Recent target-version history
 * Works with the normal **Dashboard  Updates** flow as well
 * Admin-only UI (no frontend scripts)

#### How to use

 1. Go to **Tools  Raju Core Version Switcher**
 2. Enter the exact version you want (example: `6.7.2` or `7.0.2`)
 3. Use **Check** (or wait for the automatic check) to confirm the package exists
 4. Click **Save settings**
 5. Install from this page, or open **Dashboard  Updates**
 6. When you are done, clear the target version and save to restore normal updates

#### Safety first

Changing core versions can affect themes, plugins, and site behavior.

 * Backup files and database before any change
 * Prefer testing on a staging site first
 * Confirm theme and plugin compatibility with the target version
 * Only use trusted package sources

This tool is for users who understand WordPress updates and backups.

#### Compatibility

 * Requires WordPress 5.3 or higher
 * Requires PHP 7.2 or higher
 * Tested up to WordPress 7.0
 * Multisite: configure each site under **Tools  Raju Core Version Switcher**. Network-
   wide management is not included.

#### Privacy

This plugin does not collect personal data and does not require an external account.
Settings stay in your WordPress database. Version checks request public package 
URLs from WordPress.org.

### Privacy

This plugin does not collect, store, or transmit personal user data to the plugin

## 常見問題集

### How do I rollback WordPress after a bad update?

Open Tools  Raju Core Version Switcher, enter the previous version, check that it
is available, save, then install from the plugin page or Dashboard  Updates. Backup
first.

### How do I downgrade WordPress to an older version?

Enter the older version number as the target, save settings, and complete the install.
Always backup files and the database first.

### Can I install the target version from this plugin?

Yes. After you save a valid target version, use **Install … now** on the settings
page (requires the `update_core` capability). You can still use **Dashboard  Updates**
if you prefer.

### How do I lock WordPress to a specific version?

Set the target to the version you want to stay on and save. Clear the field when
you want normal updates again.

### How do I return to normal WordPress updates?

Clear the target version field and save settings. While no target is set, this plugin
does not change WordPress update offers.

### Is it safe to change WordPress versions?

It can break incompatible themes or plugins. Backup first and test on staging when
possible.

### Does this work on WordPress multisite?

Yes for per-site use. Configure each site from **Tools  Raju Core Version Switcher**.
Network-wide management is not included.

### Will this slow down my website?

No. Scripts and styles load only on this plugin’s settings page. Nothing is added
to the frontend.

### Does the plugin send my data anywhere?

No personal data is collected. Remote requests are limited to checking public WordPress
package URLs.
