If the problem continues, deactivate it until everything is working. * Thread Starter [systerblom](https://wordpress.org/support/users/systerblom/) * (@systerblom) * [5 years, 7 months ago](https://wordpress.org/support/topic/woo-commerce-plugin-error-2/#post-13590856) * Thank you so much for your help!
