NuSOAP based Web Services stop working after Server Upgrade

ok, I've not had a chance to look into the logs yet but I keep stumbling across forum entries elsewhere about 'always_populate_raw_post_data' and 'HTTP_RAW_POST_DATA'. It sounds like this should be 'enabled' or 'on' in php.ini for NuSOAP to work correctly, at present on my server it's off, maybe it got turned off during the upgrade... :/
