Bukkit

What steps will reproduce the problem?
Any time any command is used it outputs /social help. An error is also given after startup. It initializes the plugin but fails to create any files.

What is the expected output? What do you see instead?
Instead of the plugin operating normally, no matter what command you use all you get is /social help in return

What version of the product are you using?
1.2.1

Do you have an error log of what happened?

Please read the section on the site "CraftBukkit 1.3.2-R1.0". It does not appear you are using that version of Bukkit.

If you plan on using an older version of Bukkit, you will need to use an older version of Social Network also that has been flagged as supported likely this one:
