How do you enable PHP sessions?

Find your php.ini file (which holds all the settings for PHP, and how it should work).

Under the "sessions" section, find the directive "session.save_hander." Unless you're directed otherwise, and you want sessions enabled, this directive should be set to the string "files."

If session problems arise, find the directive "session.save_path," and make sure the current path it's set to actually exists (and that PHP can write to it). PHP does not create this directory; you need to.

Still not working? Go to the directory path that session files are saved in (as noted in the "session.save_path" directive) and see if there are session files being created when you start a session in a PHP script. If they are, then your scripts are most likely the problem. If the newly created sessions are empty, make sure that you are actually putting data in them, and that you're not resetting the $_SESSION global variable anywhere.

If they aren't, then it may help to reinstall PHP, or get further assistance elsewhere.
