Rather than get more confused and more agitated, consider the beginnings of a solution given by r3sistance over on your first or second version of this question: http://www.linuxquestions.org/questi...cludes-781336/
Patience is a virtue here on LQ. You need to provide more information than what you currently have provided, and you need to NOT post the same question more than once in several different places.
Please continue this discussion in the thread I linked above, where you have had one reply already. Provide more information: maybe showing us the lines of code AROUND where the problem is occurring, will help someone diagnose the issue with you. Show us config.php lines 40-50, that would be a good place to continue.
This thread (and one or more others) will be merged and/or closed, so that your question and any replies to it, will remain in one location.
