NamelessMC

I don't know why the website no longer works, what it can be?

cache/logs/fatal-log.log

es scheint so als würde er die datenbank datei nicht finden können der fehler wird dir genau unten angezeigt.

'NamelessMC.nl2_phinxlog' doesn't exist hast du in der Datenbank rumgespielt ? 

The nl2_phinxlog table is required for the website to work - if this has been deleted then unfortunately you will need to perform a full reinstall from a fresh database, or restore from an old backup.
