I'm trying to convert my old cart to PrestaShop. Installed the ShipStation module on a test site (a subdir of my live site), followed all the instructions to set it up, but [Test Connection] insists there is a 404 error. I'm certain the url is correct. Googling for info about this, I see a few messages in the PrestaShop forums but there is apparently no solution. So I'm wondering if anyone has had any success connecting ShipStation with PrestaShop?
