Hi, I updated today to 2.4.0 and still have problems configuring fts- flatcurve. This is in my config: mail_plugins { fts = yes fts_flatcurve = yes } fts flatcurve { language de { default = yes } language en { } autoindex = yes } But it then fails to start with: doveconf: Error: Failed to get language de: Filter language=de unexpectedly not found (invalid userdb or -o override settings?) doveconf: Fatal: Error in configuration file /etc/dovecot/dovecot.conf: Failed to get language de: Filter language=de unexpectedly not found (invalid userdb or -o override settings?) If I comment out the language settings, then it starts. But a "doveadm fts rescan -A" fails with: doveadm(***): Error: fts: Failed to initialize backend 'flatcurve': languages settings: Invalid settings: No language { .. } defined doveadm(***): Error: fts not enabled for user's namespace INBOX How do I fix these 2 errors?
