Lighttpd Fails to Start (Exit code 255)

Hello, I’ve just re-installed LLMP (Lighttpd, mariaDB, & php) on my DietPi, however when I try to run lighttpd it keeps failing. I’ve tried to troubleshoot but no luck yet. Could anyone please provide some help? Thanks!

When I run /etc/init.d/lighttpd start:

[....] Starting lighttpd (via systemctl): lighttpd.serviceJob for lighttpd.service failed because the control process exited with error code.
See "systemctl status lighttpd.service" and "journalctl -xe" for details.
 failed!

When I run systemctl status lighttpd.service:

● lighttpd.service - Lighttpd Daemon
   Loaded: loaded (/lib/systemd/system/lighttpd.service; disabled; vendor preset
: enabled)

When I run journalctl -xe, these seem to be the only errors:
