NOT Resolve Fatal error: Class CI_Session_files_driver contains 1 abstract method

Head -> desk.

Hello,

That error also show on codeigniter forum open url
https://forum.codeigniter.com/printthread.php?tid=64763

Yes, because that's how you've named this thread.

Narf there no folder name contents in system directory

Contents is not a "folder name" ... use a dictionary to see what the word means.

Hi guys, I also have a simular error:

Fatal error: Class CI_Session_files_driver contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (SessionHandlerInterface::open, SessionHandlerInterface::read) in D:\wamp64\www\has\system\libraries\Session\drivers\Session_files_driver.php on line 49

I have replaced the system folder of CI 3 but still no luck. Restarting apache fixes the problem temporary. But after a while, it still comes back. Here is my working environment:

Windows 10 64 bit Pro.
Wamp Server 3.1.0
PHP Version 7.1.10
Codeigniter 3.1.6

What is very interesting, i have two other projects on this Wamp Server that are on Codeigniter 2, and they dont seem to have this problem. Any ideas or thoughts?
