This was an issue in the past. I'm surprised it's still an issue on your end; it's working on my end. But perhaps I may have fixed it without my knowledge (after beta6 was already released) when doing something. I'll look into it further. If I can't reproduce then we'll wait until beta7 to see if it resolves on your end.
Keep this install if possible. I'd like to know more about what went wrong if we can figure it out. Is this also the same one you installed those other addons? If so let me know all the addons you have installed and any settings you remember selecting.
Wow, I just deleted it. Ended up having to agree to Rules again after running Setup Wizard and got whitescreened. I think it was just a bad install, not sure why. Wanted to test some things on this install and clearly it wasn't optimal. Yes this is the one where I added some unchecked addons, hence running Setup Wizard again to remove them.
500 error specifically, No Composr .htaccess in place just a basic .htaccess to use PHP8 (AddHandler x-httpd-php83 .php) as I am stuck on 7.4 because of mail/cron issues with v10.

Hmm you got locked out on the rules agreement page? Or when you say whitescreened do you literally mean you got nothing but a white screen?
