CRITICAL Uncaught Error: Call to a member function date() on null

Hi @nicksti,

i had the same problem. Some customers told me that they got a 500 error in the checkout. I myself could not reproduce the error on any device.

I was able to solve it by downgrading to the latest Woocommerce version.

Now all customers can order as usual. Hope this helps you

I managed to fix my issue. I do not know why this happened but I updated woocommerce, wordpress and some plugins and this started happening. What made it difficult is some customers could still place an order.

Under Woocommerce -> Customers I noticed the customers who could not submit an order had a null user registration date while the ones who could place an order did not. So I went in database and updated all the customers with a user registration of 0000-00-00 to a valid date and that fixed the problem.

Looks like that was only part of it. Does anyone know where I can find the table related to the Date Registered found in the Customers page? I updated wp_users table user_registered field but the registration date is still blank. I do not even understand why some are blank and some are not.

Hello, @nicksti

I understand that some customers are unable to check out while others are.

My first recommendation is to run a conflict test, you can switch the site theme to Storefront temporarily, and then disable all plugins except WooCommerce. Check again to see if the issue persists, if not, chances are that there is a conflict, and you can then switch back your theme to the original one, and then reactivate the rest of the plugins (checking again after each plugin reactivation), until you find the culprit.

More info: https://woocommerce.com/document/how-to-test-for-conflicts/

If that does not help, please provide me the complete error message received, this is under WooCommerce > System Status > Logs.

It would be great if share your System Status Report (That will help to investigate further), it is found under WooCommerce > Status on your site.
