 * Hi there,
 * Since the last WP update there is clearly a conflict between Mailpoet and two
   other plugins:
    1. WooCommerce Appointments, from Booking WP (paid) 2. WPC Product
   Bundles for WooCommerce, from WPClever
 * Both result in a WP crash after being activated simultaneously with Mailpoet.
   Solo or without the combination with Mailpoet there is no conflict.
 * Hope you can resolve the issues soon.
 * best regards,
    Kees Alders Klokwerk-Design
