 * Hello!
 * We have an online store using WP eStore and it works perfectly, except for when
   your plugin is installed. We disabled all plugins and re-enabled them one by 
   one and found that BackWPUp was causing a critical error when using an encrypted
   download link for digital products.
 * When it’s enabled on the site, and someone clicks a “generate download link” 
   button on their purchase history page, the website throws a critcal error.
 * This error looks like the one here: [https://q8i7i8m3.rocketcdn.me/wp-content/uploads/2019/11/There-has-been-a-critical-error-on-your-website.-Please-check-your-site-admin-email-inbox-for-instructions](https://q8i7i8m3.rocketcdn.me/wp-content/uploads/2019/11/There-has-been-a-critical-error-on-your-website.-Please-check-your-site-admin-email-inbox-for-instructions)..

 * Is there anything you can do to fix this conflict?
 * Thanks!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-causing-critical-error%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hello!
 * Here is the error code:
 * “[23-Apr-2020 16:12:09 UTC] PHP Fatal error: Cannot redeclare Aws\constantly()(
   previously declared in /home/ralab/public_html/wp-content/plugins/backwpup/vendor/
   aws/aws-sdk-php/src/functions.php:19) in /home/ralab/public_html/wp-content/plugins/
   estore-amazon-s3-integration/lib/aws/Aws/functions.php on line 22”
 * This only happens when the backup plugin is activated.
 * We are using the free version of the plugin.
 * Thanks!

    seems like there
   is a conflict with the plugin `estore-amazon-s3-integration` could you disable
   that plugin then try again? TY

    since we haven’t
   heard back from you, I’m going to mark it as resolved. If you’re still having
   problems, feel free to let us know ;),
