Do you have authme? If so, you should check out the FAQ on the wiki for the setting in authme config that you must modify. I'm on mobile but if you have trouble finding it please let me know and I'll send the link as soon as I can get to my PC

Yes, yes I have the AuthMe

So read the part on the FAQ that relates to this issue.
