I use dedicated servers managed by me directly,
The versions are installed manually and I can assure you that the errors are from xenforo, could my personal configurations have something to do with it? I don't doubt it, but that's why I prefer to wait a little until everything is more confirmed.
I currently use 8.2 and 8.3 on other servers with other platforms and have had no problems of any kind. I tried xenforo on them and to fix them I have to edit and update too many php files to fix them and I barely have time to do it, so I'll wait a little longer.
Thanks for your work
