Support » Plugin: Add-on WooCommerce - MailPoet 3 » Fatal error with Woocommerce Subscriptions 2.4 installed

  • Resolved krko


    Just thought I should let you know that this plugin causes fatal error if Woocommerce Subscriptions 2.4 is installed.

    The error is:

    Fatal error: Uncaught Error: Call to undefined function is_checkout() in path-to/wp-content/plugins/add-on-woocommerce-mailpoet/includes/class-mpwa-frontend-fields.php:191 Stack trace: #0 path-to/wp-includes/class-wp-hook.php(286): mpwa_frontend_fields_init_posts_selection(‘ AND wp_posts.p…’) #1 path-to/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(”, Array) #2 path-to/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #3 path-to/wp-includes/class-wp-query.php(2602): do_action(‘posts_selection’, ‘ AND wp_posts.p…’) #4 path-to/wp-includes/class-wp-query.php(3230): WP_Query->get_posts() #5 path-to/wp-includes/post.php(1763): WP_Query->query(Array) #6 path-to/wp-content/plugins/woocommerce-subscriptions/includes/ in path-to/wp-content/plugins/add-on-woocommerce-mailpoet/includes/class-mpwa-frontend-fields.php on line 191

    Hi @krko,
    We’ve tested with Woocommerce Subscription plugin, didn’t get any problem here,

    A plugin conflict may be one of the reasons for this issue.
    To find which plugin is causing the conflict please follow these steps:

    1. Go to your plugins page > Deactivate all active Plugins
    2. Update WordPress and Enfold to the latest version if you have not.
    3. Make sure all the plugins are updated.
    4. If the problem does not persist when plugins are turned off, activate one plugin at a time and refresh until you find the plugin in conflict.

    We await the results of your plugin compatibility test.

    Thanks for your cooperation 🙂

    Best regards
