Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request. ) what does this mean?is it hosting provider problem?
yes its hosting problem only because of forbidden ness otherwise u would have encountered in a big db or php problem with wordpress
Check permissions for /wp-admin directory and files inside it. There must be at least "read" permissions and the directory should have an "execute" permission. Also check .htaccess files
