Forbidden Access

I'm getting the error below when I try to crawl my sites. I have crawled all my sites with one installation from /remote-xmlsitemap/ until recently when I started getting this message.

Forbidden

You don't have permission to access /remote-xmlsitemap/index.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Hello,

you can try to check your server's error log to possible find details on the error. Also, you can try to reinstall generator completely (remove generator folder and do clean install).
