"Remember me" feature for login in TikiWiki site not working

Question

I recently upgraded my site's installation of Tiki Wiki CMS Groupware from version 25 to version 27. I also upgraded PHP version from 7.4 to 8.3. Now the "Remember me" feature is not working and every time I visit my site I have to login again in my admin account. I tried it with different browsers and even on different computers. It is the same for other users of the site; if they return few hours later they have to login again.

I already increased those directives in php.ini but without any effect:

• session.cache_expire
• session.gc_maxlifetime
• session.cookie_lifetime

Any idea what might be causing the problem or how can I debug it?

EDIT: Added my Tiki configuration relevant to this issue:

Answer 1

There could be other causes for this, but if:

• it happens following an upgrade from Tiki 25 or anterior (and perhaps 26)
• 2 or 3 "get_user_by_cookie failed" messages are logged (tiki-syslog.php) every time you go to the site and Tiki fails to remember you
• and your "Session storage location" preference is set to Default

…then changing it to Database should workaround. That preference (session_storage) is shown in the General control panel, in the second tab (General Settings).
