When using this plugin as a “Must Use” plugin (in folder mu-plugins) I get the following PHP notice:
Undefined variable: plugin_directory
Location: app/mu-plugins/sendgrid-email-delivery-simplified/lib/class-sendgrid-settings.php:37
When I change line 31 to this the notice goes away:
public static function set_up_menu( $plugin_directory )
