I have updated the woocommerce plugin in my site to version 2.6.0 recently and now I am facing a 500 error during checkout and this error message changed as per the payment method.
I have couple of payment methods as Direct Bank Transfer and Cash On Delivery.
When I use Direct Bank Transfer I am getting an error message error Internal Server Errorand in browser console I am able to see the problem is with http://example.com/checkout-2/?wc-ajax=checkout Failed to load resource: the server responded with a status of 500 (Internal Server Error)
On the other hand when I user Cash On Delivery as payment method I am seeing an error String could not be parsed as XML.
Anyone facing similar issues with woocommerce? not sure if this is because of plugin update or any other function.
I figured it out myself finally. The problem is I messed up with the woocommerce email templates. When I undid all the changed in email templates the order slow started working normally.
During the debug process I noticed that though I get the
Internal Server Errorthe order is getting posted successfully and is visible in woocommerce admin so I was getting the errors all this while due to changed email templates where I failed to pass the order data properly into emails.
