Redstone

Redstone wont work on my server this is a real pain because me server is a roleplaying server and we would all like it to work. I know some pluggins could be the cause of this problem but the only 1 I have that i know is iffy is worldedit but I got rid of it, yet we still can't open a simple door with a button. Any clue how to fix this its very annoying.

Thank you so much!

Spoke too soon . . . The problem still remains. I got rid of builders utilities cus I no longer have a use for it but redstone is still failing me.
