I’ve just got this problem and my site is down! (I know I know I should really have a staging site to test such things first). ---

I am facing exactly the same problem, for a server migration. I need to change e-mail settings (Mandrill → SparkPost), but change is not taken into account. Edit: and I am already up-to-date: ![](https://global.discourse-cdn.com/meta/original/3X/8/0/803332b0d7dc041a528332e27463c274ebc5baf4.png) ---

Looks like my fault. I’m going to see if it’s what I think it is and submit a PR in a few minutes. If I’m right, edit launcher and remove the exit statement just after “echo done JP” ☹ ---

Sorry, folks. I left in some code I was using to facilitate debugging my changes. Thanks @jakubmierzejewski. Hopefully this will get pulled in soon and others won’t get bitten. I’ll put some procedures in place to see that I don’t do this again!
