I’ve noticed the same issue, so hopefully this will be fixed soon.
Thank you for reporting that there is an error. Would you like to check the latest version 2.4.4.
It didn’t resolve the issue, but the error changed a bit:
Old error (2.4.3):
PHP Warning: include_once(includes/class-wcmp-rest-api-integration.php): failed to open stream: No such file or directory in /home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce-myparcel/woocommerce-myparcel.php on line 153\nPHP message: PHP Warning: include_once(): Failed opening 'includes/class-wcmp-rest-api-integration.php' for inclusion (include_path='.:/usr/local/php70/lib/php') in /home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce-myparcel/woocommerce-myparcel.php on line 153\n'
New error (2.4.4):
PHP Warning: include_once(/home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce/includes/class-wcmp-rest-api-integration.php): failed to open stream: No such file or directory in /home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce-myparcel/woocommerce-myparcel.php on line 153\nPHP message: PHP Warning: include_once(): Failed opening '/home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce/includes/class-wcmp-rest-api-integration.php' for inclusion (include_path='.:/usr/local/php70/lib/php') in /home/xxx/domains/xxx.com/public_html/wp-content/plugins/woocommerce-myparcel/woocommerce-myparcel.php on line 153\n'
The issue is still that the requested file is not available. The latest version of WooCommerce (3.2.6) is installed on this website.
Thank you for reporting that the error is still there. I have changed the code back and will look for a solution.
For now the error is not longer visible, in version 2.4.5.
