 * Hi developer,
 * I got an email from WordPress when I tried to setup this plugin. Mail says there’s
   been an error with this plugin. On PHP logs, I can see:
 *     ```
       [16-Dec-2021 16:57:25 UTC] PHP Warning:  require(includes/class-wpruby-royalmail-item.php): failed to open stream: No such file or directory in ~/wp-content/plugins/royal-mail-woocommerce-shipping-calculator/wc-royal-mail.php on line 37
       [16-Dec-2021 16:57:25 UTC] PHP Fatal error:  require(): Failed opening required 'includes/class-wpruby-royalmail-item.php' (include_path='.:/opt/cpanel/ea-php73/root/usr/share/pear') in ~/wp-content/plugins/royal-mail-woocommerce-shipping-calculator/wc-royal-mail.php on line 37
       ```
   
 * When I browse includes folders, there just seems to be a admin-options.php file
   in there but not the ones being called above.
 * Using WordPress v5.8.2, Woocommerce v5.9.0

 * Hello [@a4alien](https://wordpress.org/support/users/a4alien/)
    Would you please
   remove the plugin and install it again? This should fix the issue.
