The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, XXXXXX 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.

Then This is my htaccess:

RewriteEngine on

<IfModule mod_suphp.c>
 suPHP_ConfigPath /home/XXXXX

RewriteRule ^((urllist|sitemap).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

The forum is on the main root, and vbseo folder is in root/vbseo_sitemap and the file permission is 777 on files and folders
