I have a local WAMP 3.2.0 setup to do my php coding on my local PC. It was setup and worked fine. I have recently changed Internet service providers and now my php code that access external API sites does not work. The call seems to come back with a

Failed to load resource: the server responded with a status of 501 (Not Implemented) 

response. The code when loaded on an external server does work. Any idea where I even begin to debug this?
