functie werkt niet?

ik krijg deze error:
Fatal error: Cannot redeclare forum() (previously declared in /home/fmgroup/public_html/linspin.nl/***/***/config.php:5) in /home/fmgroup/public_html/linspin.nl/***/***/config.php on line 43
als ik dit neer zet:

forum();

dit is de code:

Haal die include eens weg, wat gebeurt er dan?

Fatal error: Call to undefined function config() in /home/fmgroup/public_html/linspin.nl/forum/config.php on line 4
dan doet hij het
maar als include er boven staat dan doet hij het weer niet dus kan ik niks includen??

in welke bestand staat de functie forum?

map:
forum
bestand:
config.php

en ik gebruik nu op:
forum/index
