Sometimes when you try access
PhpMyAdmin you will get session errors that it says
Error during session start;
To fix this error is very simple, all you have to do is to login into your server with terminal and run this command
chmod 777 /var/lib/php/session
Second solution is to edit your
php.ini file and make changes below:
session.save_path = "/var/lib/php/session"
That's all you need to do and your problem is solved.
