Hello, we have been running Dokuwiki for a good while on Debian 12 servers. To quell the latest nag screen I ran the Upgrade plugin via CLI, but it reported that our PHPversion was too old (7.3 I think). We upgraded the PHP to 8.3 because we needed it for some other software. Apparently this broke Dokuwiki (Jack, I think): blank screen at startup, calling doku.php yields error about CSS compilation, no styles load, etc.
Okay. I tried a fresh install of both the latest stable and nightly builds. install.php runs but always always gives the error
Superuser - illegal or empty value
no matter what I input. Dokuwiki without ACL isn't so useful for us, so I'm stuck.
My best guess is that my PHP configuration is hinky, but I don't know where to look in Dokuwiki for specific clues. Other PHP apps on the system are working fine. Thanks much for any suggestions
