Okay so I've tried a lot of permission plugins (currently trying bPermissions) for Bukkit and I have the same problem with all of them: They work perfectly fine... everything goes how it should until a friend of mine actually tried to do a command. I deleted other plugins just in case it was one of those that was messing it up but nope. They can't people in the groups (verified that they are in the groups using the actual plugin commands) can't perform the commands that they should be able to perform. I'll attach screenshots of all the files and the log.
