 * Hi [@verbre](https://wordpress.org/support/users/verbre/) ,
 * Thanks for reaching out!
 * I understand that after updating to PHP 8, you noticed this warning message on
   your products page, is this correct?
 * I would like to clarify that this is only warning message and it should have 
   no impact on the functionality of the site. Please could you confirm that nothing
   on your site is being affected as a result of this warning message?
 * As a first step can you check that you have the latest version of WooCommerce
   core installed? If not, please can you update this and see if the warning message
   disappears.
 * Should the issue persist, please can you share a copy of the following:
    - **System Status Report**: navigate to **WooCommerce** → **Status**. Select`
      Get system report` and then `Copy for support`.
    - **Fatal Error log**: Share a copy of any fatal error log found under **WooCommerce**
      → **Status** → **Logs**.
 * Once you have these, please share them in your response here.
 * Cheers!

 * I checked everything you asked for. The site works correctly, there is only this
   error message. Nothing in the logs. I put you the link of the report : [https://drive.google.com/file/d/1cUjdSdIgUZbTXNlJxKB4jACeBRkzA8kr/view?usp=sharing](https://drive.google.com/file/d/1cUjdSdIgUZbTXNlJxKB4jACeBRkzA8kr/view?usp=sharing)

 * Hello [@verbre](https://wordpress.org/support/users/verbre/),
   Thank you for sharing
   the report.Your theme has some outdated templates, [you can start by checking this guide to update them](https://woocommerce.com/document/fix-outdated-templates-woocommerce/).
   If that doesn’t help, then please try disabling all plugins except WooCommerce
   as well as switching to [Storefront](https://woocommerce.com/storefront/). If
   the problem is not present after doing so, then you know there was a plugin conflict.
   You can enable the plugins one by one again to find the culprit.If you’re not
   comfortable doing all of this on the live version of your site, you can create
   a staging environment using [WP-STAGING](https://wordpress.org/plugins/wp-staging/).
   Let us know how it goes!
