 * I am using
    WordPress – Version 4.9.10 WooCommerce – Version 3.5.0 WooCommerce
   Square – Version 1.0.33 I am getting following error log for any payment.
 *     ```
       Array
       (
       [0] => stdClass Object
       (
       [category] => AUTHENTICATION_ERROR
       [code] => UNAUTHORIZED
       [detail] => This request could not be authorized.
       )
   
       )
       Order status changed from Pending payment to Failed.
       ```
   
 * I have deactivated the plugin and re-enable and try again. Same error.
    I am 
   unable to update the WordPress version and WooCommerce version. What can I do
   for this?

 * Hi there,
 * Usually, disconnecting and reconnecting to Square will resolve this.
    You can
   do this from WooCommerce–> Settings–> Integration.
 * Having said that, it’s important to the security and functionality of your site
   that you keep up with the latest version of WordPress/ WooCommerce/ all extensions;
   moving forward, you’ll want to find a way to update.
 * Best,
 * Ross

 * We haven’t heard back from you in a while, so I’m going to mark this as resolved–
   if you have any further questions, you can start a new thread.
