 * I have just installed WooPayments and all has been authroised etc. When I click
   on WooCommerce > Settings > Payments an error message appears saying “Error retrieving
   settings”
 * I am also unable to check box the section for Credit / Debit Cards but Apple 
   Pay and Google Pay allow the check box to be ticked.
 * If I try and save the settings, an error message appears, “Error saving settings”
 * In the WooCommerce > Settings > Logs tab, there are fatal-errors like this (details
   changed for display purposes):
 * Uncaught Error: Call to a member function get_cart() on null in /homepages/14/
   mydatabase/htdocs/mywebsite/wp-content/plugins/order-delivery-date/includes/orddd-
   process.php:4092
 * Can someone please help with this as we’re trying to get our website up and running.
 * Thank you

 * Hi [@steve_williams_wp](https://wordpress.org/support/users/steve_williams_wp/)
 * Based on your explanation, it seems like there could be a conflict with the Order
   Delivery Date plugin. The error message is indicating that a function is trying
   to be called on a null value, which could be causing the issues you’re experiencing
   with WooPayments. The best way to determine this is to:
    - Temporarily switch your theme to Storefront or Twenty Twenty-Four
    - Disable all plugins except for WooCommerce and WooPayments
    - 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.](https://woocommerce.com/document/how-to-test-for-conflicts/)
 * I hope that helps! Let me know once you have done a conflict test!

 * Hi Shameem
 * I have disabled the aforementioned Order Delivery Date plugin and yes, that appears
   to be the problem. I will contact the providers and see what they say.
 * Thank you for the quick response.
