Support » Plugin: WooCommerce » HTTP ERROR 500 after checking completed order

  • Resolved aleksicbre2017


    (woocommerce is latest version)
    Hello, when I mark order as complete (via this ), I got error page HTTP ERROR 500

    But when I update order status via WC order page I got this: Just white page

    But in both cases, order are marked successfuly as completed, but no emails are sent.

    How to fix?

  • Anyone ?

    It is really important, does anyone have answer_ Thanks!

    I dont really want to become bored, but this is important to me. Also, I had same problem a year ago, but IDK how it was fixed. I hope this also will help others. Thanks!

    I’m having this exact same issue as well. When I update the order to “Completed”, I get a HTTP ERROR 500. Any support for this?

    Same happens here.
    I’ve just updated WP to 4.9.1, Woocommerce to 3.2.5, and the problem continues.

    The biggest problem is that automatic emails are not being sent.

    In my case, the problem only happens when clicking the tick from the order list.
    But if I go to Edit the Order and change status from there, everything works fine.

    Same problem here…. 🙁

    500 errors are caused by PHP Fatal Errors, which are obfuscated by WordPress. Search through your server’s error logs to find the exact error and script location; it is often caused by a customization or plugin which is referencing a deprecated class/function.

    Marking as resolved. This was most likely a plugin conflict when another plugin had a function tied to the save action for orders. Given the amount of time, if this is still an issue, we would recommend the steps at the below link, and if that doesn’t help you locate the issue, create a new thread.
