WooCommerce links broken after migration

So basically, I migrated from byethost to x10hosting a couple of weeks ago. Seemless experience,

However, this certain problem has been bugging me for the past few weeks. Whenever I edit an order and hit save, the page redirects me to a 404 error page, which says the following:

Oops! That page can’t be found.
It looks like nothing was found at this location. Maybe try a search?

It’s obviously not a server fault, because it works perfectly on a fresh installation of WordPress on the same host.

Any assistance would be greatly appreciated.
