Page not found after manual Create Order when Product Item added

I spent a good amount of time troubleshooting my own site and also using Google to find a solution. I was unable to correct the problem on my own, but I do have specific detail after the troubleshooting.

When I manually create an order using WooCommerce (from my admin login), I am able to successfully create an order if I enter nothing (default entries upon add order). I can also add order if I enter the customer info, payment type, customer notes, etc. I can also update an order if I do the same.

The problem seems to start when I add product. If I create order (or try to update an existing order) after adding a product, I am presented with “Oops! That page cannot be found” (basically a 404 error). The same result occurs if I try to update an existing order and add product.

Bottom line is I can create and update orders just so long as I do not add product. As soon as add product is part of the entry, I get the 404.

Please help!
