Everything went well, I have created a New Customer account successfully, Placed an Order and Proceeded to Checkout.
But when I tried to click Continue button from BILLING INFORMATION TAB with the Ship to this address option selected, I can't go to the next step.
I checked on Network tab and found that checkout/onepage/saveBilling status is returning:
(failed) Or Failed to load resource: net::ERR_CONNECTION_RESET.
I tried to select the second option which is Ship to different address, and the SHIPPING INFORMATION TAB was loaded.
But then again, when I entered a new address then click the Continue button or choose Use billing address, I still got the error but this time, it is checkout/onepage/saveShipping
Did anyone experience this kind of error before?
Looking forward to a solution.
Note: It is a fresh install. No modifications made.
EDIT: FOUND THE SOLUTION ALREADY
DISABLED SOME EXTRA SHIPPING METHODS LIKE UPS, DHL, AND ETC. Then it works
