I am having an issue with Magento's onepage checkout.
Everything was working fine, I had tested a few orders with success. However, today I merged css/js from the magento admin and afterwards I noticed that during the onepage checkout process it gets stuck at the billing address.
I "unmerged", cleared magento cache, cleared browser cache and cookies and still the issue remains.
There are no errors in firefox developer tools and I see the following under the network tab when clicking "Continue":
POST https://www.example.com/checkout/onepage/saveBilling/ 200 OK
POST https://www.example.com/checkout/onepage/getAdditional/ 200 OK
I have randomly tried the solutions of "similar" issues that I found while searching magento stackexchange and nothing has worked or hasn't been relevant to my installation.
The issue does not occur with the default theme so I am assuming it is to do with the custom theme being used.
Any help will be greatly appreciated.
saveBilling
andgetAdditional
should return a JSON response. IN your case, for some reason it returns an empty response. That's all I could see on a first glance. Try debugging step by step thesesaveBillingAction
andgetAdditionalAction
methods in the onepageController.prototype.js
? I am trying to remember whether I had done any test orders after the last security update I installed from magento. I shall look in to that!
