I've been banned on my own server for entering any raidable base. Any way to fix?

What does it say?

ah yes, go into the permissions for Raidablebases and UNCHECK "banned"

To un ban yourself from events.
Only use that permission to NOT allow a player/rank to not be able to participate.

Enjoy

Very sorry for the late reply. Work keeps me busy. Every time I tried to enter a raidable base area
in my own server it would say [Raidable Bases] Banned

I did exactly as Misticos said. Went into /perms and revoked any permission for 'banned' for myself within the
Raidablebases and I'm back in action. THANK YOU!

i didnt tell you to do this but ok

Well, I have the same problem. Worked fine, I've done 25 bases with all sort of different people on my server, when I tried to do 26th, I could not enter the base. I get message [ Raidable bases ] banned.
I have checked all perms, all looks good, I am not banned in perms. I have restarted server twice, reloaded pligin, revoked all perms and granted them again, nothing works at all.
Everyone can enter except me. There've been 8 people inside the area at once, I couldn't. Any solution? REINSTALL? 

if it says you're banned then you have the permission yourself or in a group you belong to that has the permission

perhaps you are in 2 groups?
