I just created a new version 22.214.171.124-b1 that should fix the issue. You can download it from the ‘my account’-page. Can you please let me know if that one works? I saw I used a function that was implemented after WC 2.3.7.
If it doesn’t work can you tell me what happens? Any error messages (with WP_DEBUG enabled) ?
Ofcourse I will help you. Please first try the newest v126.96.36.199-b3 that I just placed on your account page.
If that doesn’t work, please let me know what error you see and what versions of WordPress and WooCommerce you are using. And, if you allow me, provide me with a temporary admin login to your page so I can debug myself, you can send it to admin @ soft79.nl.
