I am trying to import my wordpress.com blog into my wordpress.org blog (hosted by Network Solutions) and either the connection times out or this message occurs.
500: Internal Server Error
This error is generated when a script running on the server could not be implemented or permissions are incorrectly assigned for files or directories.
Temporarily disable any rewrite rules by renaming your .htaccess file if it exists. Ensure that any CGI or Perl scripts have at least .755 permissions. If trying to run PHP and you get this error, you may have an invalid php.ini or your cgi-bin, or may be using your php.dat file in this folder.
