 * When I turned on the plugin, the following message appeared:
   **Fatal error**:

 * Hi [gorzewski](https://wordpress.org/support/users/gorzewski/) 
 * Thank you for this message. We have already analyzed the error message, and it
   comes out that the problem is on the WooCommerce, as you can see in their plugin
   forum. [https://wordpress.org/support/plugin/woocommerce/](https://wordpress.org/support/plugin/woocommerce/)
 * Please downgrade the WooCommerce plugin to version 8.4.0, our plugin will work
   correctly. If there is a new update that fixes the version 8.5.0 error, you will
   be able to upgrade WooCommerce again.
 * Best regards

 * Hi
 * We have just released the Flexible Checkout Fields 3.6.0 update, containing the
   proper fixes for the problem you’ve reported. It’s compatible with the latest
   WooCommerce version. So please simply do the update.
 * If the WordPress updater hasn’t informed you about the newer versions available,
   please check for the updates manually, choosing the Dashboard tab > Updates >
   Check Again option.
 * Please let me know if you have any further questions or if there is something
   more I can help you with.
 * Kind regards,
 *  Plugin Support [rzepsen](https://wordpress.org/support/users/rzepsen/)

 * Hi,
 * Please run a debug on higher php versions. We’re experiencing fatal errors reaching
   the cart page on servers running php higher than 8.0.
 * Thanks.
