Title: Fatal error: Class ‘WC_REST_Controller Last modified: December 15, 2016 --- # Fatal error: Class ‘WC_REST_Controller * [sasquatchms](https://wordpress.org/support/users/sasquatchms/) * (@sasquatchms) * [9 years, 5 months ago](https://wordpress.org/support/topic/fatal-error-class-wc_rest_controller/) * Hi, * I installed the plugin and out of curiosity viewed the source code of the page in Chrome. I then clicked the HREF link in the string (redacted): * `` * I got this error (redacted): * `Fatal error: Class 'WC_REST_Controller' not found in /XXXX/XXXX/XXXX.com/wp- content/plugins/woocommerce-shipment-tracking/includes/class-wc-shipment-tracking- rest-api-controller.php on line 11` * I know this error is showing another plugin which you do not control. But maybe you can point me in the right direction on how to start resolving? Or tell me if this error is preventing your plugin from working properly?
