 * Hi [@autobooks](https://wordpress.org/support/users/autobooks/) ,
 * Thanks for reaching out!
 *     ```wp-block-code
       Warning: Undefined array key “id” in /home/autobook/public_html/wp-content/plugins/woocommerce/includes/gateways/paypal/class-wc-gateway-paypal.php on line 856
       ```
   
 * This is a PHP warning rather than a fatal error, so your site should still be
   running fine.
 * I see you mentioned that WooCommerce hasn’t been updated yet, I’d recommend starting
   there. Warnings like this can sometimes be addressed through updates, so updating
   to the latest version may resolve the issue.
 * As a precaution, I’d suggest performing the update on a staging site first. After
   updating, test the areas of the site where you originally noticed the warning
   and check whether it appears again. If everything looks good on staging, you 
   can then proceed with the update on your live site.
 * If the warning continues to appear after updating WooCommerce, please feel free
   to get back. It would be helpful to include your **System Status Report** when
   you follow up. You can find this under **WooCommerce → Status → Get system report
   > Copy for support** . This will give us some additional information about your
   WooCommerce and WordPress environment and help us investigate further.
 * Let us know how it goes!
