I started to receive this error a few days ago. My hosting provider believes that there may be an in the program.
'502 - Web server received an invalid response while acting as a gateway or proxy server.
There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy) contacted the upstream content server, it received an invalid response from the content server.'
The version is 'Standalone Sitemap Generator (PHP) v3.0, 2009-05-19' and it is running in a Windows/IIS 7 environment. Any help would be greatly appreciated.
