Magento: SOAP/PHPfpm error
Depending on the version of Magento used, the soap does not work properly and may return the following error message: "Uncaught SoapFault exception: [Client] looks like we got no XML document."
The problem is not just a bad server configuration, but a bad Magento design, that does not take into account the case of executing PHP in an FPM environment. Thus, SOAP requests generated by Magento include double headers (not compliant with the SOAP specification) and generate an error. http://www.magentocommerce.com/boards/m/viewthread/229253/
