Woocommerce Checkout Errors

Hi there.

I am having some issues with my woocommerce store. Clients are experiencing trouble when checking out. They fill in all the required fields, and check the t’s & c’s – but then receive a ‘blank woocommerce error’ showing only a red exclamation mark with no error message.

I have tried the checkout from my end and am able to place orders, however many clients are having this problem.

Here are the ‘fatal errors’ in my woocommerce log:

I have updated my theme (astra theme) and my plugins as well as deactivated plugins one by one over time – and the same problem seems to still occur.

Please can you assist with any suggestions on how to find the problem?

thank you
