Is your auto translation setup not working quite how you expected? See if you can fix it using the advice here!
Check you haven't run out of characters
Run /translation_usage to see! Either upvote the bot, buy an upgrade pack, a tier on Patreon or wait for next month to get more characters.
Check the bot has the right permissions
It needs to be able to send messages, view channels and view message history in all the channels it's running in. If you're using style 8 or 9, it also needs to be able to create webhooks. If your messages are being reacted to with a warning shield, it normally means JakeBot has a permission issue.
Check the FROM language is part of your selected Translator
In your setup, make sure the language being translated from (you can translate TO any of the languages) is available in your selected translator with /languages. Not all languages are available with all Translators. Change your Translator, if you have premium, with /settings translator [option].
Check the old settings menu (old_settings) isn't open
If the old entirely button based setup system menu /old_settings or J!translation_settings is open in a channel translations will not commence in that channel until it has been closed.
Check it isn't disabled
Run /settings automatic_translation view [setup] to see if it's been disabled or not.
Check the channel is correct
Run /settings automatic_translation view [setup] to make sure the channels are all correct
Check you have any special roles that may be required
Run /settings automatic_translation view [setup] to see if it's been setup with a requirement to have a certain role for it to translate you.
Is it diverting somewhere?
Run /settings automatic_translation view [setup] to see if it's diverting to a channel you haven't noticed.
Check both blacklists
Run /settings automatic_translation view [setup] and /settings global_blacklist list to see if your trying to translate a message that's being blacklisted.
Are you trying to translate between one and three words?
Then run/settings2 extras view_options and see if "Single Word Translation" and "Three Word Translation" are allowed.
Are you trying to translate a message that looks like a bot command?
Then run/settings2 extras view_options and see if "CMD Activation Messages" are allowed.
