 * Unable to start 20.8.2. I get:
 * Plugin could not be activated because it triggered a fatal error.
 * Fatal error: Cannot redeclare add_readygraph_plugin_warning() (previously declared
   in /var/www/vhosts/essexham.co.uk/httpdocs/wp-content/plugins/subscribe2/extension/
   readygraph/extension.php:6) in /var/www/vhosts/essexham.co.uk/httpdocs/wp-content/
   plugins/email-newsletter/extension/readygraph/extension.php on line 54

 * Many thanks,

 * [@frequencycast](https://wordpress.org/support/users/frequencycast/):
 * Thank you for pointing out: it will be fixed with next update.
 * For now, you can change:
    email-newsletter/extension/readygraph/extension.php:
   line 54 from `function add_readygraph_plugin_warning() {` to `function add_ee_readygraph_plugin_warning(){`
 * and email-newsletter/readygraph-extension.php: line 120
    from `add_action('admin_notices','
   add_readygraph_plugin_warning');`
 * to
 * `add_action('admin_notices', 'add_ee_readygraph_plugin_warning');`

 * OK. Changes made as suggested – Still getting a fatal error, this time on a different
   line:
