Human Authorization add-on has been updated today for containing a little fix which I've discovered shortly after releasing miniBB 3.5. The change is inside of the addon_authorize.php which you have to update on your forum.

I didn't considered it important, but the practice shown it could lead to a PHP error message like: PHP Warning: session_id(): Cannot change session id when session is active in...; obviously this especially affects PHP version 7.4 and up.

I appreciate reports from Karel for this issue.
