I have made myself a tekkit server and I cannot figure out how to get the Permissionsex, Essentials, and Griefprevention plugins to work correctly, I have followed the tutorials to the letter and when my members log in, they are not able to do anything, no building, no commands, nothing. I have exhausted myself looking for answers to this issue and turn to you in desperation. Please help this hapless noob.
