Hi Bill,
If the Cross Sell products showing on a single product page that means they are already set. But if you are not able to see the cart page while using the default cart page, there might be something else that is the reason behind your problem.
I would like to suggest troubleshooting the following common issue to help us to recognize the reason.
1.Theme Related Issue
2.Plugin Conflict
3.Theme Update related issue
4.Child Theme Related issue ** if you have activated it.
5.CSS/JS Customization
6.Disabling Cache
7.Disabling CDN
If you discover that an issue is coming from a custom code or 3rd party plugin, kindly consult with a developer or contact the plugin author. Please note that we do not provide support for custom codes and 3rd party plugins.
I would also request that you activate any of the default themes, like TwentyTwenty, and check if the issue persists or not. If the issue persists, please provide login credentials for your site in a secure note to examine it further, including:
– WordPress Site URL & Login URL
– WordPress Admin username/password
To create a secure note, click the key icon underneath any of your posts.
NOTE: I have tried to check your website listed in your Themeco Account, but it shows an ERR_CONNECTION_TIMED_OUT error.
Thanks
