Basically the title says it all. I posted screenshots of the perms i added on discord #support-international on the FabioZumbi12 dev discord. (Somewhitedude#6154) is my username. Another user in the chat was confused also because I added all the right perms. Any idea what went wrong? thanks.

Basically you don't need to add none of the permissions. The default perms to players start to use redprotect is already given. Remember that you need a perm plugin and optionally (recommended) vault plugin for spigot version too.
