On https://delisouth.nl/druivenpitolie-250-ml/ an extra row of related products (“andere suggesties”) is visible, while the related product option via theme settings is put off.
The upsell field is used and these products are shown as they should.
Do you know where this extra row comes from?
Also weird: one loggin in, the related prodcts that are shown there, are different from when you’re not logged in.
Please check how it works with the default WordPress theme just to check whether the issue is with our theme or not.
Because the upsells are default WooCommerce functionality and our theme doesn’t influence.
If it works fine with the default WordPress theme then deactivate all the third-party plugins and provide with the admin panel login details of the website then we will troubleshoot with the theme plugins.
