I need a senior Codeignitor developer to fix issue.

Description

I have developed a small CI project for my client. It is working fine when i have developed it on my hostgator hosting. But when i moved it to client's Site ground hosting it is not working. Only default controller is opening, other controller is not opening. Ex : a) [login to view URL] b) [login to view URL] First link is opening default controller without any issues, but second link is diplaying 500 error. I know it is small configuration issue. I need some one who is good in Codeignitor to fix this.
