I've installed Standalone XML Sitemap Generator software on my website [external links are visible to admins only] - according to the instructions in the howto-install.pdf.
However, a generator sitemap is not accessible via the url
[external links are visible to admins only] - and a message appears on the screen:
Internal Server Error (Title: 500 Internal Server Error)
The server encountered an internal error or misconfiguration and was Unable to complete your request.
Please contact the server administrator, and inform [external links are visible to admins only] 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.
What should I do?
