Bukkit

Describe to us the issue that you're having:

I was really happy to see an update (thank you dev :) and I always do the following beforehand. Start a new screen (ubuntu dedi server) build the latest bukkit with build tools (craftbukkit1.8.8.jar) download the plugin into my folders and finally run the plugin by itself. and as soon as it booted up I got this same error message in my logs 3 times in a row... :( Once inside the game it is shown in green as if the plugin was working ok so I wonder...

Is this normal behaviour? Is this just me?

Made a mistake posting the error log file, corrected

You need to explicitly enable the use of offline mode in the bpermissions config.yml
