Problems moving gitea instance to new server

I had to move my personal gitea instance to a new server. In doing so i had to change OSes and Gitea version (upgrade) – not my choice per se.

copied the app.ini, db backup, and filestore to new server and the service tries to start, but fails with this error message:

Unable to register cron task update_mirrors Error:translation is missing for task “update_mirrors”, please add translation for “admin.dashboard.update_mirrors”

What does this mean, and how can I fix it? New host is FreeBSD, Gitea version: 1.18.3
