Hello, do you have access to the detailed debug log then we can check the error? Please send me the error log. Let me know also the wordpress/woocommerce and php versions you are running, also if you are using woocommerce HPOS options.
Is this error happening before any other settings saved?
Please review how the status slug and name are set (do not start with number, do not use special chars, limit 17 chars)
Hi,
Thank you so much for your quick response.
Anyway, I’ve already found the problem and fixed it.
It occured because the name of the order status I created ends with %.
Now, it’s all works out. So, I’m gonna go ahead and change the status of this post to resolved.
Thanks again
