PHP Session Id changes between pages

Question

I have a problem where i am losing the PHP session between 2 pages.

The session_start() is included in a file called session-inc.php into every page requiring a sess

Answer 1

SOLUTION: session.auto_start = on in file: php.ini

It solved the issue of re-generating session id on page reload (page refresh / change pages).

The issue appeared after the update of CPanel (and included Multi PHP), even the php version remained the same.

The PHP.ini file didn't had that variable at all. Went in Cpanel -> MultiPHP INI Editor -> Editor Mode (not Basic, in basic you do not have this setting) and added the line. Press Save.

TIPS / WHEN TO USE THIS SOLUTION: To determine if that is the problem, put a line at the very beginning and at the very end of your index.php file to check the session id. Use function: session_id(); Navigate through pages / reload the page. If the session_id value changes the problem is not in your code and this solution should solve your problem (the session is lost outside of your code).

I also tried to verify the availability of saving session on the web server (session.save_path) but, even if it was a lead, it was not the case. I imagine this is a "feature" of Cpanel with MULTIPHP UPDATE that will happen quite often.
