I just downloaded new version of XML sitemap generator, and I installed it. After installing I cannot access my sitemap generator: [external links are visible to admins only]. I received the error message:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [external links are visible to admins only] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request. "
Please try to help me out. Thanks.
