I have developed a project in CodeIgniter 2. It works well in any browser. And I can login and explore my account successfully in (Chrome, IE, OPERA, SAFARI and FIREFOX) on Windows(Safari, Chrome, Firefox) on Android(Safari, Firefox, Chrome) on iOS 9.3. Also, the login works in any browser on OS X, but after exploring some pages, the session are lost.
Has anyone run into the same problem?
