Onyx has three tools available;

*   Re-install default plugins
*   Restart PHP
*   Regenerate `wp-config.php` file

This article runs through each of those tools and their uses..

#### Accessing Onyx Tools

1.  You'll need to start by [logging in to your Onyx dashboard](https://onyx.io/login).
2.  From your Onyx dashboard, click on the site you'd like to access.

3.  From the **Settings** drop-down on the left click **Tools**.

#### Re-install default plug-ins

For new WordPress sites created via the Onyx dashboard we pre-install the LiteSpeed caching plugin that handles both file and database caching.

If you are on the Pro plan or above and you have the CDN enabled, you will also see an **Onyx CDN** plugin installed. If this has been removed, or is not present and CDN is enabled for the site then it too will be re-installed along with the LiteSpeed plugin

If you have migrated your site to Onyx from elsewhere it's likely these plugins won't be installed.

If you should find these plugins missing from your site they can be re-installed from within the Onyx dashboard by simply clicking the **Re-install default plugins** button.

#### Restart PHP

If you've made changes to PHP configuration using a `.user.ini` file, you may wish to restart PHP to ensure changes are applied immediately. Simply click **Restart PHP** to restart the PHP handler.

#### Regenerate wp-config.php file

If you've made changes to or lost your `wp-config.php` file, you can regenerate a fresh one with our default settings. Simply click **Regenerate wp-config.php** to recreate the default `wp-config.php`.

#### Disable PHP Functions

You can disable specific PHP functions by adding them in a comma separated list, for example:

`popen,exec,system,passthru`

Once you have added the functions you would like to disable, click the **update** button.
