When I go to click on Op prison it says "You are not whitelisted on this server" Why does it say this??
They might be preparing for a reset. But, I am not certain about that. Whitelisting means that you have a list of people that can join the gamemode/server. If a player isn't in that whitelist, they cannot join that server. This is a brief description of whitelisting for Minecraft servers. If you need more information, search it up for yourself.
OpPrison is currently in the process of being reset. It is unknown when the release will be, but its coming. At this time, no one is available to go into OPPrison. Since your question has been answered, I will close this. Please keep an eye out for more information on it's release.
