After update server error

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 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! 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.

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!
