Any MelooonCensor command executed by the console doesn't work. All that happens is this error appearing in the log:

This exception appeared in v1.2.5.

It doesn't matter whether there are any arguments. "mcensor" does exactly the same as "mcensor add flower": The exception I posted above.
I hope you'll be able to fix that :)

Check to be sure the sender is an instance of a Player, before trying to interact with the Player object.

"Caused by: java.lang.ClassCastException org.bukkit.craftbukkit.command.ColouredConsoleSender cannot be cast to org.bukkit.entity.Player"

The console cannot be cast to a player.

Use a check like: if(sender instanceof Player)

To ensure your player object is not null.
