just in case this actually make any difference, the reason that i reinstall Discourse is because i just finished the full verification from mailgun today.
To save myself from trouble, i am trying to reinstall everything.
Sorry my bad, I wanted to remove some extra verboseness that @pfaffman added (we don’t need to be notified of every single expected default) and I did not realize an empty if then statement was not allowed in bash. Thanks for the fix.
