I have the same issue as #1537. I am using WAMP server. When I visit http://localhost/index.php I get redirected to http://localhost/index.php/installation https://github.com/alextselegidis/easyappointments/blob/e45fcf30b579a9a2a03bbbb35efb96556f1ad426/application/config/config.php#L27 If I remove $request_uri I get the correct url. $request_uri is what adds the back slash https://github.com/alextselegidis/easyappointments/blob/e45fcf30b579a9a2a03bbbb35efb96556f1ad426/application/config/config.php#L33
