The latest stable version of PHP is 8.1.4 * If you’re still experiencing this error, would you mind checking if, by chance, your server is blocking the function putenv() on their side? * I hope to hear from you soon!

Can you please follow these steps? * **1**. Check if there is an update for your theme and your plugins. **2**. Run a conflict test to see if the issue is caused by a conflict with your theme or with another plugin. Check out the documentation here: [https://docs.woocommerce.com/document/how-to-test-for-conflicts/](https://docs.woocommerce.com/document/how-to-test-for-conflicts/).** 3**. As the last step, if none of the above works, reinstall WordPress and WooCommerce( first test on your staging site). * It’s a good idea to update in a staging environment first. Ask your hosting company if they have staging site facilities or use the free [WP Staging](https://wordpress.org/plugins/wp-staging/) plugin. * Let us know how it goes. * Thread Starter [mez00o](https://wordpress.org/support/users/mez00o/) * (@mez00o) * [4 years, 1 month ago](https://wordpress.org/support/topic/warning-include_once-2/#post-15520581) * this domain is on my own cloud server red hat * and if it is not compatible with your plugin how it work fine with PHP 7.4 perfectly * just I get this issue when I make update PHP * finally * I try all of your steps and one of them with a different theme and only one plugin woo now I’m sure the issue in woo with PHP 8 * do you have another suggest * [hegenberg](https://wordpress.org/support/users/hegenberg/) * (@hegenberg) * [4 years, 1 month ago](https://wordpress.org/support/topic/warning-include_once-2/#post-15520728) * Hi [@mez00o](https://wordpress.org/support/users/mez00o/) * Is this fatal error log showing after some specific action on the site or breaking some functionality?
