After Update to 2.0.17 error log is flooded with errors from guests

[Cypheros]

I updated some days ago but now my error logs are flooded with warnings and errors. Thousands per hour.

8: Undefined index: is_guest
.../Sources/Subs.php
Line: 2809

Source code:

Code Select Expand

2805: // Start up the session URL fixer.
2806: ob_start('ob_sessrewrite');
2807: ob_start(function ($buffer) {
2808: global $context;
==>2809: if (!$context['user']['is_guest'])
2810: return $buffer;

It seams guests have missing context entries.

My guess is one or both of the following two items to check... could be pointing to the wrong session info storage directory on your server, or it could also include folder/file permission issues, could be both

Where I can find the setting for the session info storage directory?
It worked well with 2.0.15 but update to 2.0.17 broke something.

All PHP files in /Sources/ are 644 only Load.php is 604

PHP is 7.3

Changed Load.php to 644 but problem still exists.

iirc there's a thread about changes to the handling of cookies in 2.0.16 (and 2.0.17). Maybe you've fallen foul of the changes. Possibly try flushing out all sessions and have everyone log-in again?
