 * After updating Woocommerce 8.4 to 8.5.1 I immediately get a server error. This
   means my entire server is no longer running and I have to reboot it. But the 
   page still causes a Network error attempting to retrieve a resource.
 * What could be the reason?
   Greetings Felix

 * Here’s a step-by-step guide:
    1. **Deactivate WooCommerce**: If you can access your WordPress Admin, navigate
       to ‘Plugins’, find WooCommerce, and click ‘Deactivate’.
    2. **Delete the Current Version**: After deactivation, click ‘Delete’ to remove
       the current version of WooCommerce. Don’t worry, your data is safe.
    3. **If you can’t access WordPress Admin**: Access your WordPress files with FTP/
       SFTP/SSH/File Manager and remove the directory: `/wp-content/plugins/woocommerce`
    4. **Download WooCommerce 8.4.0**: Click [this download link from the WordPress repository](https://downloads.wordpress.org/plugin/woocommerce.8.4.0.zip)
       to download WooCommerce 8.4.0 file to your computer.
    5. **Install the Downgraded Version**: In your WordPress Admin, go to **Plugins**
       > **Add New** > **Upload Plugin**. Upload the file you just downloaded and activate
       the plugin.
    6. **Check Your Site**: Ensure that everything is running smoothly and that no 
       data was lost during the downgrade.

 * Hello, Thank you very much, I had already done that. The server is running smoothly
   again, but I can’t install the new update without problems. I’m thinking about
   security vulnerabilities and stuff like that.

 * Hey there, [@p3xhosting](https://wordpress.org/support/users/p3xhosting/)! Thanks
   for contacting us. I’m happy to help you.
 * Do you have the **Order Attribution feature **set to **enabled** and, you also
   have Web Application Firewall (WAF) rules set up in your hosting configuration?
   If you do, we are currently looking into this issue on 8.5.1. You can read more
   about it **[here](https://developer.woo.com/2024/01/16/woocommerce-8-5-1-issues-with-web-application-firewalls-modsecurity/)**.
 * If this is the case, you can check the links on the blog post on how to proceed
   on each case.
 * Please let us know if you have any questions.
 * Have a wonderful day!
