Enabling Debug Mode for User Plugin

The cPanel end-user plugin provides a debug mode for use troubleshooting problems. Debug mode is disabled by default.

You should enable debug mode if the plug-in displays the "an error has occurred" message.

Create the plugin configuration by copying the default file:

cp /usr/local/xvarnish/ui/cpanel/configuration.php-default /usr/local/xvarnish/ui/cpanel/configuration.php

Open this new file using your favorite editor:

nano /usr/local/xvarnish/ui/cpanel/configuration.php

Change constant DEBUG_MODE to a boolean true value as shown below. Save your changes.
```
define('DEBUG_MODE', true);
	
```
Reload the cPanel end-user plugin to see additional debug information on the error.
Revert DEBUG_MODE to boolean false once you are finished.
