NEED HELP ON SERVER PLEASE!

Hello everyone, I just made a server about 2 days ago and its pretty hard i can tell you that. Well for one, My factions wont work. When people on the server try to /f create [name] its says they dont have permission even though i put the command for eveyone to use in GroupManager. Second, To do any changes like ranks (making people diff ranks) i have to restart the server and do it or else it just re-dos what i put in. Can someone help? And some Plugins like Towny dont let my Moderators or Builders build or open doors or do anything. Im in desperate need of help.
