Can’t update order from admin backend

Hi,

Great plugin btw. Currently using it with WooCommerce 3.6.5 and WP 5.2.2, only for the decimal quantity feature.

Everything’s working fine, price calculation ok, order total ok. BUT, when there’s a decimal quantity in an order, I can’t update the order from backend, e.g. changing status from on-hold to processing, etc. The “Update” button is clickable, but doesn’t do anything, it’s just idling no matter how many times I’ve clicked it.

If I change the decimal quantity to whole number, then the Update button suddenly works again.

Any idea why this happens? I’ve checked the error logs, console, nothing there.

I’ve tried installing it on a different site, but got a different error. Whenever I edit the quantity from the backend, and save, the loader animation won’t end. It’ll continue to rotate endlessly. The new quantity is saved though. But this is a different story, the main problem is above.

Thanks in advance.
