Error 406: What is it and how can I fix
HTTP-protocol error "406 Not Acceptable" means that the format or encoding of the page are not supported by the robot.
If this error occurs when you run the indexing, the most likely cause of its occurrence - the main page of your site is not supported by the robot returns the content type.
Check as well - maybe set up your web server software or the site does not properly generate the header Content-Type.
MySitemapGenerator searches the URL only on pages that form the HTML-code, respectively, must return the title of «Content-Type» with the meaning «Text/HTML».
robot, which produces mobile site indexing (service Sitemap Mobile ), also supports WML, cHTML-content.
You can use the viewer HTTP headers a> to check the type of content pages.
