Error thrown Using $this when not in object context

Hi Peter!

It’s possible that there might be a theme/plugin conflict after doing the updates.

Try switching to the [Twenty Seventeen theme](https://wordpress.org/themes/twentyseventeen/), and see if the issue remains. If so, try disabling all of your plugins except WooCommerce. Then try testing again to see if the issue persists. If that resolves your issue, enable each plugin one by one while continuing to test until you find the plugin that causes the issue.

If you don’t want to do this on your live site, you can clone your site to a staging environment, where you can test without affecting your users.

If your host doesn’t provide staging facilities, a simple way to do it is using the free WP Staging plugin:
https://wordpress.org/plugins/wp-staging/

Let us know if you still need help after this process.

I will also mark the other thread you started as resolved and we can continue in this one.

We haven’t heard back from you in a while, so I’m going to mark this as resolved – if you have any further questions, you can start a new thread.
