Hi,
As newbie I find the plugin useful, and the duplicate checker works great.

its a shame that the alive checker is broken though. Any chance of a fix for it?

This is the message I get

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/etc/lsb-release) is not within the allowed path(s): (/home/:/usr/lib/php:/tmp) in /home/a3869553/public_html/wordpress/wp-content/plugins/ping-list-checker/ping.php on line 169

Regards
