So since the famous update to 2.1.3, I am having a serious issue where no one can checkout on my website.
Basically, you can go through all the steps and at the end, when you click place order, it goes back to the billing page but the URL will change to checkout/order-pay, which is the Checkout Endpoints in the Woocommerce settings. I use Paypal Advanced Gateway (latest update). If I have a typo on my settings for my Paypal account, I will get an authentication error so the plugin seems to still be working but for some reason I will get trapped in a loop.
I also use HTTPS and tried to disabled the plugin and unchecked "force https" on woocommerce as well as the HTTPS plugin. Still no luck. Note that I didn't change any settings for the past 2 months and it always worked. I installed WPML this morning (after the woocommerce upgrade). Not sure if it's related but I tried disabling it just to make sure and still no luck. Same for Total cache. I pretty much disabled all my plugins and I still have the same issue.
Anyone is experiencing the same problem?
