I upgraded from Magento CE 1.8.1 to 22.214.171.124 and now the FedEx and USPS shipping modules I had set up do NOT work, as in they do not show in the shipping step at checkout.
At first I thought it might be a Theme / Template issue since I am finding that virtually ALL of the Themes that I have tried, that worked fine with 1.8.1 have problems somewhere with 126.96.36.199 so I set it to the RWD Default theme that was part of the 188.8.131.52 Magento CE install, but it did not fix the shipping problems.
I was using the following in 1.8.1 with no problems:
Free Shipping FedEx USPS UPS
Now the only two I can get to work are UPS and Free Shipping. The UPS module is really not that great as it does not factor return accurate shipping values.
Any help would be appreciated. ( I have cleared the cache and have tried enabling / disabling the shipping options to no avail.)
