 * Hello,
    I get this error on the frontend and backend. [24-Jul-2022 08:39:25 UTC]
   PHP Warning: array_key_exists() expects parameter 2 to be array, string given
   in /home/MY_USERNAME/public_html/dev/wp-content/plugins/woocommerce/includes/
   admin/helper/class-wc-helper-options.php on line 58
 * Default theme is on with minimal Wooocommerce activate and the issue is still
   there.
    [I’ve found this thread](https://wordpress.org/support/topic/warning-array_key_exists-expects-parameter-2-to-be-array-boolean-given-in-3/)
   but the solutions there didn’t help. What should I do?
 * Thanks

 * Hi there,
 * Thanks for reaching out.
 * I need to check your website setup to help you further. It will be great if you
   could share your current System Status Report. You can get it by navigating to
   the `WooCommerce / Status` section of your site. Once there, click on the `Get
   system report` button and then copy it by clicking on the `Copy for support` 
   button. Then paste it here in a comment.
 * Best,

 * Hi there [@odedta](https://wordpress.org/support/users/odedta/)!
 * Thanks for sharing the system status report.
 * In the thread that you’ve shared and the Github link here: [https://github.com/woocommerce/woocommerce/issues/22176](https://github.com/woocommerce/woocommerce/issues/22176),
   users mention that `woocommerce_helper_data` option in the database was corrupted.
 * You could try dropping/deleting the row with the option name `woocommerce_helper_data`:
 * ![](https://d.pr/i/24FCdl+)
 * Once done, you could reconnect your site with WooCommerce.com by going to **WooCommerce
   > Extensions > My Subscriptions**, this will regenerate the `woocommerce_helper_data`
   option with correct data.
 * Let us know how that goes! 🙂

 * Hello,
 * Deleting that row helped, the error is gone. I don’t think that the subscriptions
   was connected but it’s possible that it was connected at some point and that’s
   why the data was corrupt.
 * Thanks for the quick help! 🙂
