I updated to 2.1.1. I've gone through the common issues post and updated permalinks which fixed a lot of my problems (with "My account", etc.), thanks. Our biggest issue right now is when you submit an order it doesn't go to the order-received endpoint, it shows a 404 error. I'm wondering if it's because I set my pages up manually after installing WC and my checkout page isn't set up properly (I don't have checkout - pay). I understand many of those pages are now gone and replaced with endpoints. Also wondering if it could be my payment gateway plugin (although it says it is 2.1.1 compatible)http://wordpress.org/plugins/authorizenet-aim-payment-gateway-for-woocommerce/ Let me know if you need anymore info, I hope this makes sense!
