Hello gerold1968
Thank you for your reply.
There might have been a misunderstanding because we have been suggesting this snippet to activate the Revision for Products long before HPOS was introduced. Here is a forum thread from July 2021 with a similar case.
Could you please confirm that you added this snippet to your site and it did not work? May I ask how you added the snippet?
To help you further, I’d like to understand more about your setup.
Could you please send me a copy of your site’s System Status?
You can find it via WooCommerce > Status.
Select Get system report and then Copy for support.
Once you’ve done that, you can paste the text in https://gist.github.com
After that, you can paste the Gist link here in your reply.
Looking forward to your response. ??
