Than I gave myself superadmin privilegies
As MrPresident asked previously, while you are connected to your server, please run "ulx who" from your game console.
If you are "superadmin" group, then it will list you as superadmin.
If you are any other group, then that may be your issue.
Also, Just because Ftpje made DarkRP, doesn't mean he wrote doorsgroups or spawnpoints tools.
You would need to contact the individual author of those tools.
DarkRP and group access controlled by ULX have little to do with many of the tools made for either.
