New Server error help

[UnfLooter]

Hello, I have started a new server, and I'm new to the whole thing. Any tips, tricks, or pointers in my way would be very much so appreciated.
The first thing that happened when I put an addon in my server and then launched it was a giant error spam with this.

[ERROR] addons/durgzmod/lua/entities/durgz_pcp/init.lua:93: attempt to index global 'server_settings' (a nil value)
1. fn - addons/durgzmod/lua/entities/durgz_pcp/init.lua:93
2. unknown - addons/ulib/lua/ulib/shared/hook.lua:105

Now I'm new to lua and all of this so I have no clue what to do or how to fix it. Please help, Thank you.
(Please explain how I fix the error or give me a link to fix all future errors without having to ask.)

post the code so we can actually see whats wrong

with

ghetto solution but it works

[UnfLooter]

Could you explain why i would have to do this so i understand it?

[thecubanpimp]

[QUOTE=UnfLooter;49748426]Could you explain why i would have to do this so i understand it?[/QUOTE]

on the if statement the code checks for a boolean which cannot find (i dont know why to be honest, maybe youre in singleplayer?) and it breaks, just remove the boolean check because you dont really need it

[UnfLooter]

Alright Thanks.

Much appreciated thanks. Have a great day!

It actually looks like you dont have ulx nor ulib installed. Get them here: [URL="http://www.ulyssesmod.net"]http://www.ulyssesmod.net[/URL]
