Purged the Nginx cache automatically after making website changes. Uses the *new* HestiaCP API, released in 1.6.0.

== Description ==

**Important**: Hestia 1.6.12 fixes an issue where purging the cache could make the website unavailable, resulting in a 502 error. If you aren't using this version, please upgrade!

This plugin automatically purges the Nginx cache after you make a website change such as updating a post or changing your theme.

You also have the ability to manually purge the cache using a button in the WordPress admin bar.

== Installation ==

Manage your Hestia cache in a better way by using these steps to install the plugin.

= Installing and activating the plugin =

1. Install Hestia Nginx Cache automatically or by uploading the ZIP file.
2. Activate the plugin through the *Plugins* menu in WordPress.

= Getting API access =

If you are not the server administrator, you can skip this step.

1. Login as the system administrator account and navigate to the server configuration page.
2. Enable API access for all users in the Security > System section.
3. In the "Allowed IP addresses for API" box, enter both `127.0.0.1` and your server's public IP.

= Generating an Access key =

1. Log in as your regular user in the Hestia Control Panel and navigate to your user settings.
2. Click on the "Access Key" button, and create a new access key with the `purge-nginx-cache` permission. *Make sure to save the Secret key, as you will only see it once.*

If you do not see the "Access Key" button, it means that the feature is disabled on the server. If you are the administrator, refer to the previous section to enable it. If not, contact your server administrator so that they can enable the API access.

= Configuring the plugin =

1. Navigate to the plugin's settings in the Settings submenu in the sidebar.
2. Enter the Access key and Secret key from the previous section in the appropriate boxes.
3. For the hostname, use the HestiaCP same hostname you use to connect to the control panel. Same thing for the port.
4. For the username, enter the username that is owner of the domain name you are trying to clear.

== Frequently Asked Questions ==

= How do I generate an Access key? =

Refer to the Installation tab for information on how to configure the plugin.

= Can I manually purge the cache using the plugin? =

Yes, you can. Once the plugin is installed and activated, you will see a "Purge Nginx Cache" button in the admin bar.

= I am experiencing issues with the plugin. What do I do? =

You can try to resolve the problem by purging the cache, deactivating the plugin, or disabling Nginx caching in Hestia.

If you are using Cloudflare and get an error when purging the cache, enter the hostname of the Hestia install in the settings, not the site URL.

If your issues persist, do not hesitate to contact me via email!
