Error when sign in as journal manager

The managing editor of our journal can no longer get into the site as the manager. He gets the following msg:
Fatal error: Call to undefined function session_is_registered() in /home/jctonline/journal/lib/pkp/classes/session/Session.inc.php on line 64

The reviewers periodically get the same message. As editors we can still get in journal without an issue.

Hi @jlmcqueen,

I suspect you’re running an old version of OJS; PHP has deprecated the session_is_registered function and it has been removed from recent releases of OJS. I’d suggest upgrading.

Thank you! Can someone walk us through the update process? Our support person is no longer working with us, so we are flying by the seat of our pants.

Hi @jlmcqueen,

The upgrade process is documented in docs/UPGRADE; it’ll need someone who has some general server administration skills. The complexity of the upgrade will depend whether your system has been modified, and how old it is.
