I have previous opened a ticket but there was no solution found.
I have a website, it is fully updated and when I update an order status I get a 404 page not found error. If I enter again in the order it will update eventually.
I have enabled the plugin "Health Check & Troubleshooting" so I diasbled every plugin and enabled the default wordpress them. Then I enabled the woocommerce plugin and updated an order. That far everything's okay. Afterwards I enable WPML Multilingual CMS and WooCommerce Multilingual & Multicurrency, as the enclode image, and the 404 error occured after updating an order.
I have no idea what is going on but after enabling wpml the site admin get very slow. Please do you have any idea what is going on?
Also, earlier today I received an email from the site reporting a technical issue. It was when I tried to update an order. The issue:

Thank you for contacting us and I'd be happy to assist.
I couldn't reproduce this issue on a test website, which suggests something specific to your website or server is involved.
To troubleshoot this, I'll need to see how WPML and WooCommerce are set up on your website. Can you please share temporary admin login details, in reply to this message?
I'll also need your permission to download a clone/snapshot of the website, in case it needs to be investigated on a different server.
Note: Your next reply will be private and making a complete backup copy is recommended before sharing the access details.
First, thank you for waiting as I completed the troubleshooting around this error report.
I've tested your website's clone on 3 different server environments and couldn't reproduce the error while updating the WooCommerce orders.
- I tested the order update process from the orders list page and the single order edit screen page in the admin area
- Used different admin user accounts for this testing
- Tested with different orders, order statuses, and ordered products combinations
Reviewing the reported errors from your server's log, in detail, when the order update process fails for you on the first attempt, the system can't seem to find/access the code that does exist on the server.
( because it works on the subsequent attempts )
And it is not just limited to code in WPML plugins. The same is also happening for code in other plugins like 'yith-woocommerce-wishlist' and 'woocommerce'.
To avoid this, here are my recommendations:
1. Please make sure WordPress, plugins, and the active theme are updated to the latest versions, at all times
2. Check with your website's host to see if any server/CDN level throttling is involved, where more resources are only made available when the processing demand increases. That would explain the timeout that results in the server not being able to find/execute the complete code on the first attempt. But then works afterward, without making any other changes.
I hope these findings are helpful and let me know if your hosting support team has any more insights to add here.
