After I click install for visitor-maps, it displays the following message.
Fatal error: error traversing GeoLite City database file - perhaps it is corrupt? Try reinstalling it. in /home/MY_db/public_html/wp-content/plugins/visitor-maps/include-whos-online-geoip.php on line 454
and after that, all my admin page and including the hole website in not working instead it displayes the above Fatal error. I want to deactivate the plugin but I can't do nothing. Because it displays only the above error and I can't access the WP admin/plugins page.
