Hi,
The translate option isn’t available anymore, we get this message:
{“code”=>404, “message”=>“Maximum daily translated text volume exceeded”}
It still works for me I think. Just checked Diego’s thread.
It is about translator rate limit 
By the way I changed the category to Off-Topic as it is not related with Kodular, it is about Discourse.
The message says it all 
I got the same message just now:/
There are some server limitations, this can be a reason for a daily translate limit. Btw. I think max translations/sec would be better as daily translation number does not actually show how much requests the translator has to process.
