Hey there!
I see what you mean – the code is showing up on the checkout block:

Looking at the page’s code, there’s no clear indication of what’s making that CSS show up on your page.
It looks like it might have something to do with security, based on this:

However, we haven’t had any other reports of this problem and I can’t reproduce it on my end. That leads me to think that there’s something on your site that’s forcing that code to show up.
This kind of problem is usually caused by either a conflict with your theme or with another plugin.
?
The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
Please do let me know how that goes!
