[Rspamd-Users] Error 500 on rspamc learn_spam

[Will van Gulik]

I could fix the ignore_whitelist errors, however I'll need some
additional help with the "rspamd_language_detector_init", reinstalling
the package didn't help. Any other ways I can dig to fix that ?

Also note that on a machine where I don't have the additional errors
with my classifier output, I also have the 500 error. Any ideas on that
one ?
