I recently installed both Precious Stones and Simple Clans on my 1.5.2 minecraft server. I have been unable to get precious stones to work properly. It appears green in the plugin list, but when I attempt to place a diamond block nothing happens. When I type the command /ps the only two command that appear are /ps blacklistcommand [command]
and /ps blacklistcommand clear.

I have tried using the build "R: 9.5.7 for CB 1.5.2-R0.1 Apr 05, 2013" on the bukkit page as well as a few different builds from jenkins.

Nevermind. It seems Ops do not get the permissions by default...
