Resolved Lacking Permissions?

In Skyblock, I was trying to warp to another island but it said I lacked the permission to do so. I also tried visiting/warping to my plots in Creative and Survival but I lacked the permissions for that action there. I cannot speak in chat either because it says I need to "join a channel" but when I attempt to join a channel, it says I lack the permission to do that action. These are the examples that I found with this sort of error. There might be other things, but I am unsure as I have not checked since these are the most notable things I've encountered. :/
