One of my customer got a error after enabling my app Who's There, the reason was, a server configuration, he need to set the "allow_url_fopen = On" in his php.ini

After some search I found out the php function I use (file_get_contents) was not a good idea and it was causing the new issue above.

I didn't search more to found out why people said not to use the php function file_get_contents(), but i't was easy to change the function to use the Curl method.

I also fix a error on the page when a IP is block.

Regards
