I've set myself to Super Admin but I don't have any permissions? Help!
If you're certain that you've set yourself to Super Admin but still have no permissions, or your permissions seem to be resetting when you restart your server, first check to make sure that you're not running any other admin mods on your server, as this may be causing conflicts. Make sure you've not got ULX/ULib and that, if you're running DarkRP, that you've disabled FAdmin (If you're unsure how to do this, see here: https://darkrp.miraheze.org/wiki/LUA:Remove_FAdmin).
If you're certain that you're not running any other admin mod on your server, it's possible that you've accidentally removed all permissions from Super Admin, but don't worry, there's a command for that! Simply run the following command in your server console: xadminassignallperms "Super Admin" this will reassign the "All Permissions" node to the Super Admin group and should allow you to use all xAdmin commands.
