Check that WooCommerce is activated. * I would recommend you upgrade to Version 2 on WooCommerce or if that is not possible try using an earlier version of this plugin 0.1.5 or 0.1.4 which would have worked with your version 1.3.2.1. * regards * Steve * Thread Starter [monzu02](https://wordpress.org/support/users/monzu02/) * (@monzu02) * [13 years ago](https://wordpress.org/support/topic/fatal-error-746/#post-3739734) * Thank you for your reply but is it safe? * [perkinwarbeck2013](https://wordpress.org/support/users/perkinwarbeck2013/) * (@perkinwarbeck2013) * [13 years ago](https://wordpress.org/support/topic/fatal-error-746/#post-3739809) * I, too, would like to know if it is safe. * Plugin Author [swicks](https://wordpress.org/support/users/swicks/) * (@swicks) * [13 years ago](https://wordpress.org/support/topic/fatal-error-746/#post-3739813) * is what safe? * Thread Starter [monzu02](https://wordpress.org/support/users/monzu02/) * (@monzu02) * [13 years ago](https://wordpress.org/support/topic/fatal-error-746/#post-3739835) * [@swicks](https://wordpress.org/support/users/swicks/) will you please let us know its safe to use or not?
