Permissions for guest not set [RESOLVED]
I've been using vanilla since early 2.x version and haven't updated in a long while.
Because of security issues i'm trying to update my vanilla installation from 2.3.1 to the latest 2.8.3, a big step.
I followed the steps outlined here: https://docs.vanillaforums.com/developer/installation/self-hosting/
I made a copy of the live environment, created a dev DB copy, copied over all the new files, ran upgrade process and did all the things listed in the steps (delete plugins that are in core now).
After that i needed to update my theme because it used old methods and/or old ways of doing things.
After that, the forum worked as intended and looked good. The only thing is, when i logout, i see no categories at all...
It just says "No categories were found.". I of course checked all settings in the backend and most of all the roles and permissions, but all seem OK.
After quite a while of desparation i dived into the core code, all the way to the source bootstrap file which creates the session etc. As far as i can see, the session for an anonymous user gets created blank and then is immediately used for checking rights. The blank session has no rights (of course) and thus, all permission checks for all categories fail and nothing is shown.
As far as i can tell, this is a Vanilla bug, but as nobody else here is complaining about it, it's probably not.
The only possible sollution to this that i found by googling was to update the php version to 7.2+ which i did, but no luck (and can't see what impact this would have on this).
Anyone that can help?
