Errors in production.log "article_plain is missing a template for request formats: text/html"

Technical assistance

Hi,

we have migrated zammad to a new host.
Everything is working fine.
The only thing are some errors in production.log that we cannot explain(because everything is working).

Any hint what causes these errors?

Sorry, I never saw this issue before. Did you try to restart your Zammad instance?
