HelpNether Help

Ok so i basically made a portal to the Nether but when i got there i could neither build or destroy Blocks and neither could any of my friends. Im owner of the server and my friends are admin so i dont see the problem. And in my server properties nether-allowed is set to true. So why isnt it letting me build or destroy blocks in the nether??

allow-nether is just the variable for letting the server generate the nether itself.
If you are using per-world permissions, you will have to give yourself the proper permissions.

your permission isn't set right...
