Hello.
I'm not a professional programmer, but I'm trying to help my student intern so that he can help me this summer. We are running into a very strange problem that neither of us, nor my other programming supporters, can figure out.
On my system, I'm running xampp with my codeigniter-framework website without any problems.
We've installed the exact same xampp with the same files on my student's computer, but when he tries to run localhost, this is the error message he gets:
Code:

WorkingWebs is the local folder under which the cirwep website is installed. These are all Codeigniter files that are having issues, but we can't figure out what the problem is though we have spent many days on this issue.
We've checked all the ini files and .conf files under xampp, and they both work without problems on my machine.
Anyone have any ideas where we could look next for a problem?
Strange problem - CodeIgniter Error - won't start
