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 * Thread Starter [golansky](https://wordpress.org/support/users/golansky/) * (@golansky) * [2 years, 4 months ago](https://wordpress.org/support/topic/bug-flexible-checkout-fields-classes-plugin-php/#post-17331614) * Hi [@rzepsen](https://wordpress.org/support/users/rzepsen/), * Downgrading WooCommerce is not a solution. * When you release an updated version of your plugin, please include the solution I mentioned, which involves wrapping this lines with an isset function ? - This reply was modified 2 years, 4 months ago by [golansky](https://wordpress.org/support/users/golansky/). * Plugin Support [rzepsen](https://wordpress.org/support/users/rzepsen/) * (@rzepsen) * [2 years, 4 months ago](https://wordpress.org/support/topic/bug-flexible-checkout-fields-classes-plugin-php/#post-17334658) * Hi [golansky](https://wordpress.org/support/users/golansky/) * Thank you for a detailed explanation. Could you send an error message in feedback? * This problem may be related to other plugins used in your shop. Please try to isolate an issue, by disabling plugins which are not our or WooCommerce. Then please enable plugins individually, delete the cache, and check if the problem still exists. * If yes, please test the plugin again, but now using [Storefront](http://wordpress.org/themes/storefront/)– official WooCommerce theme. It will help us identify a possible conflict with your theme. * Please, let me know about the result. * Best Regards, * Thread Starter [golansky](https://wordpress.org/support/users/golansky/) * (@golansky) * [2 years, 4 months ago](https://wordpress.org/support/topic/bug-flexible-checkout-fields-classes-plugin-php/#post-17338359) * [rzespen](https://wordpress.org/support/users/rzepsen/) I am just reporting an error that I have fixed myself in your plugin. It is not related to other plugins but rather to PHP 8.0 and above, as well as the new version of WooCommerce. - This reply was modified 2 years, 4 months ago by [golansky](https://wordpress.org/support/users/golansky/). - This reply was modified 2 years, 4 months ago by [golansky](https://wordpress.org/support/users/golansky/). * Plugin Support [rzepsen](https://wordpress.org/support/users/rzepsen/) * (@rzepsen) * [2 years, 4 months ago](https://wordpress.org/support/topic/bug-flexible-checkout-fields-classes-plugin-php/#post-17344628) * Hi * That $base[ $key should be an array.
